+      and can be 0: OP_CALL then sets `top' to last_result+1, so
+      next open instruction (OP_CALL, OP_RETURN, OP_SETLIST) may use `top'.
+
+  (2) In OP_RETURN, if (B == 0) then return up to `top'
+
+  (3) For comparisons, B specifies what conditions the test should accept.
+
+  (4) All `skips' (pc++) assume that next instruction is a jump

-** Dynamic library loader for Lua
-** See Copyright Notice in lua.h
-*
-* This  Lua library  exports a  single function,  called loadlib,  which is
-* called from Lua  as loadlib(lib,init), where lib is the  full name of the
-* library to be  loaded (including the complete path) and  init is the name
-* of a function  to be called after the library  is loaded. Typically, this
-* function will register other functions,  thus making the complete library
-* available  to Lua.  The init  function is  *not* automatically  called by
-* loadlib. Instead,  loadlib returns  the init function  as a  Lua function
-* that the client  can call when it  thinks is appropriate. In  the case of
-* errors,  loadlib  returns  nil  and two  strings  describing  the  error.
-* The  first string  is  supplied by  the operating  system;  it should  be
-* informative and useful  for error messages. The second  string is "open",
-* "init", or  "absent" to identify  the error and is  meant to be  used for
-* making  decisions without  having to  look into  the first  string (whose
-* format is system-dependent).
-*
-* This module contains  an implementation of loadlib for  Unix systems that
-* have dlfcn, an implementation for Windows,  and a stub for other systems.
-* See  the list  at  the end  of  this  file for  some  links to  available
-* implementations of dlfcn  and interfaces to other  native dynamic loaders
-* on top of which loadlib could be implemented.

-  (providing more output space) before each call.
-
-     The library also supports reading and writing files in gzip (.gz) format
-  with an interface similar to that of stdio.
-
-     The library does not install any signal handler. The decoder checks
-  the consistency of the compressed data, so the library should never
-  crash even in case of corrupted input.

-   The opaque value provided by the application will be passed as the first

-   opaque value.
-
-   zalloc must return Z_NULL if there is not enough memory for the object.
-   If zlib is used in a multi-threaded application, zalloc and zfree must be
-   thread safe.
-
-   On 16-bit systems, the functions zalloc and zfree must be able to allocate
-   exactly 65536 bytes, but will not be required to allocate more than this
-   if the symbol MAXSEG_64K is defined (see zconf.h). WARNING: On MSDOS,
-   pointers returned by zalloc for objects of exactly 65536 bytes *must*
-   have their offset normalized to zero. The default allocation function
-   provided by this library ensures this (see zutil.c). To reduce memory
-   requirements and avoid any allocation of 64K objects, at the expense of
-   compression ratio, compile the library with -DMAX_WBITS=14 (see zconf.h).
-
-   The fields total_in and total_out can be used for statistics or
-   progress reports. After compression, total_in holds the total size of
-   the uncompressed data and may be saved for use in the decompressor
-   (particularly if the decompressor wants to decompress everything in
-   a single step).

-/*
-    deflate compresses as much data as possible, and stops when the input
-  buffer becomes empty or the output buffer becomes full. It may introduce some
-  output latency (reading input without producing any output) except when
-  forced to flush.
-
-    The detailed semantics are as follows. deflate performs one or both of the
-  following actions:
-
-  - Compress more input starting at next_in and update next_in and avail_in
-    accordingly. If not all input can be processed (because there is not
-    enough room in the output buffer), next_in and avail_in are updated and
-    processing will resume at this point for the next call of deflate().
-
-  - Provide more output starting at next_out and update next_out and avail_out
-    accordingly. This action is forced if the parameter flush is non zero.
-    Forcing flush frequently degrades the compression ratio, so this parameter
-    should be set only when necessary (in interactive applications).
-    Some output may be provided even if flush is not set.
-
-  Before the call of deflate(), the application should ensure that at least
-  one of the actions is possible, by providing more input and/or consuming
-  more output, and updating avail_in or avail_out accordingly; avail_out
-  should never be zero before the call. The application can consume the
-  compressed output when it wants, for example when the output buffer is full
-  (avail_out == 0), or after each call of deflate(). If deflate returns Z_OK
-  and with zero avail_out, it must be called again after making room in the
-  output buffer because there might be more output pending.
-
-    If the parameter flush is set to Z_SYNC_FLUSH, all pending output is
-  flushed to the output buffer and the output is aligned on a byte boundary, so
-  that the decompressor can get all input data available so far. (In particular
-  avail_in is zero after the call if enough output space has been provided
-  before the call.)  Flushing may degrade compression for some compression
-  algorithms and so it should be used only when necessary.
-
-    If flush is set to Z_FULL_FLUSH, all output is flushed as with
-  Z_SYNC_FLUSH, and the compression state is reset so that decompression can
-  restart from this point if previous compressed data has been damaged or if
-  random access is desired. Using Z_FULL_FLUSH too often can seriously degrade
-  the compression.
-
-    If deflate returns with avail_out == 0, this function must be called again
-  with the same value of the flush parameter and more output space (updated
-  avail_out), until the flush is complete (deflate returns with non-zero
-  avail_out).
-
-    If the parameter flush is set to Z_FINISH, pending input is processed,
-  pending output is flushed and deflate returns with Z_STREAM_END if there
-  was enough output space; if deflate returns with Z_OK, this function must be
-  called again with Z_FINISH and more output space (updated avail_out) but no
-  more input data, until it returns with Z_STREAM_END or an error. After
-  deflate has returned Z_STREAM_END, the only possible operations on the
-  stream are deflateReset or deflateEnd.
-  
-    Z_FINISH can be used immediately after deflateInit if all the compression
-  is to be done in a single step. In this case, avail_out must be at least
-  0.1% larger than avail_in plus 12 bytes.  If deflate does not return
-  Z_STREAM_END, then it must be called again as described above.
-
-    deflate() sets strm->adler to the adler32 checksum of all input read
-  so far (that is, total_in bytes).
-
-    deflate() may update data_type if it can make a good guess about
-  the input data type (Z_ASCII or Z_BINARY). In doubt, the data is considered
-  binary. This field is only for information purposes and does not affect
-  the compression algorithm in any manner.
-
-    deflate() returns Z_OK if some progress has been made (more input

-/*
-    inflate decompresses as much data as possible, and stops when the input
-  buffer becomes empty or the output buffer becomes full. It may some
-  introduce some output latency (reading input without producing any output)
-  except when forced to flush.
-
-  The detailed semantics are as follows. inflate performs one or both of the
-  following actions:
-
-  - Decompress more input starting at next_in and update next_in and avail_in
-    accordingly. If not all input can be processed (because there is not
-    enough room in the output buffer), next_in is updated and processing
-    will resume at this point for the next call of inflate().
-
-  - Provide more output starting at next_out and update next_out and avail_out
-    accordingly.  inflate() provides as much output as possible, until there
-    is no more input data or no more space in the output buffer (see below
-    about the flush parameter).
-
-  Before the call of inflate(), the application should ensure that at least
-  one of the actions is possible, by providing more input and/or consuming
-  more output, and updating the next_* and avail_* values accordingly.
-  The application can consume the uncompressed output when it wants, for
-  example when the output buffer is full (avail_out == 0), or after each
-  call of inflate(). If inflate returns Z_OK and with zero avail_out, it
-  must be called again after making room in the output buffer because there
-  might be more output pending.
-
-    If the parameter flush is set to Z_SYNC_FLUSH, inflate flushes as much
-  output as possible to the output buffer. The flushing behavior of inflate is
-  not specified for values of the flush parameter other than Z_SYNC_FLUSH
-  and Z_FINISH, but the current implementation actually flushes as much output
-  as possible anyway.
-
-    inflate() should normally be called until it returns Z_STREAM_END or an
-  error. However if all decompression is to be performed in a single step
-  (a single call of inflate), the parameter flush should be set to
-  Z_FINISH. In this case all pending input is processed and all pending
-  output is flushed; avail_out must be large enough to hold all the
-  uncompressed data. (The size of the uncompressed data may have been saved
-  by the compressor for this purpose.) The next operation on this stream must
-  be inflateEnd to deallocate the decompression state. The use of Z_FINISH
-  is never required, but can be used to inform inflate that a faster routine
-  may be used for the single inflate() call.
-
-     If a preset dictionary is needed at this point (see inflateSetDictionary
-  below), inflate sets strm-adler to the adler32 checksum of the
-  dictionary chosen by the compressor and returns Z_NEED_DICT; otherwise 
-  it sets strm->adler to the adler32 checksum of all output produced
-  so far (that is, total_out bytes) and returns Z_OK, Z_STREAM_END or
-  an error code as described below. At the end of the stream, inflate()
-  checks that its computed adler32 checksum is equal to that saved by the
-  compressor and returns Z_STREAM_END only if the checksum is correct.
-
-    inflate() returns Z_OK if some progress has been made (more input processed
-  or more output produced), Z_STREAM_END if the end of the compressed data has
-  been reached and all uncompressed output has been produced, Z_NEED_DICT if a
-  preset dictionary is needed at this point, Z_DATA_ERROR if the input data was
-  corrupted (input stream not conforming to the zlib format or incorrect
-  adler32 checksum), Z_STREAM_ERROR if the stream structure was inconsistent
-  (for example if next_in or next_out was NULL), Z_MEM_ERROR if there was not
-  enough memory, Z_BUF_ERROR if no progress is possible or if there was not
-  enough room in the output buffer when Z_FINISH is used. In the Z_DATA_ERROR
-  case, the application may then call inflateSync to look for a good

-
-     This is another version of deflateInit with more compression options. The
-   fields next_in, zalloc, zfree and opaque must be initialized before by
-   the caller.
-
-     The method parameter is the compression method. It must be Z_DEFLATED in
-   this version of the library.
-
-     The windowBits parameter is the base two logarithm of the window size
-   (the size of the history buffer).  It should be in the range 8..15 for this
-   version of the library. Larger values of this parameter result in better
-   compression at the expense of memory usage. The default value is 15 if
-   deflateInit is used instead.
-
-     The memLevel parameter specifies how much memory should be allocated
-   for the internal compression state. memLevel=1 uses minimum memory but
-   is slow and reduces compression ratio; memLevel=9 uses maximum memory
-   for optimal speed. The default value is 8. See zconf.h for total memory
-   usage as a function of windowBits and memLevel.
-
-     The strategy parameter is used to tune the compression algorithm. Use the
-   value Z_DEFAULT_STRATEGY for normal data, Z_FILTERED for data produced by a
-   filter (or predictor), or Z_HUFFMAN_ONLY to force Huffman encoding only (no
-   string match).  Filtered data consists mostly of small values with a
-   somewhat random distribution. In this case, the compression algorithm is
-   tuned to compress them better. The effect of Z_FILTERED is to force more
-   Huffman coding and less string matching; it is somewhat intermediate
-   between Z_DEFAULT and Z_HUFFMAN_ONLY. The strategy parameter only affects
-   the compression ratio but not the correctness of the compressed output even
-   if it is not set appropriately.

+    deflate compresses as much data as possible, and stops when the input
+  buffer becomes empty or the output buffer becomes full. It may introduce some
+  output latency (reading input without producing any output) except when
+  forced to flush.
+
+    The detailed semantics are as follows. deflate performs one or both of the
+  following actions:
+
+  - Compress more input starting at next_in and update next_in and avail_in
+    accordingly. If not all input can be processed (because there is not
+    enough room in the output buffer), next_in and avail_in are updated and
+    processing will resume at this point for the next call of deflate().
+
+  - Provide more output starting at next_out and update next_out and avail_out
+    accordingly. This action is forced if the parameter flush is non zero.
+    Forcing flush frequently degrades the compression ratio, so this parameter
+    should be set only when necessary (in interactive applications).
+    Some output may be provided even if flush is not set.
+
+  Before the call of deflate(), the application should ensure that at least
+  one of the actions is possible, by providing more input and/or consuming
+  more output, and updating avail_in or avail_out accordingly; avail_out
+  should never be zero before the call. The application can consume the
+  compressed output when it wants, for example when the output buffer is full
+  (avail_out == 0), or after each call of deflate(). If deflate returns Z_OK
+  and with zero avail_out, it must be called again after making room in the
+  output buffer because there might be more output pending.
+
+    If the parameter flush is set to Z_SYNC_FLUSH, all pending output is
+  flushed to the output buffer and the output is aligned on a byte boundary, so
+  that the decompressor can get all input data available so far. (In particular
+  avail_in is zero after the call if enough output space has been provided
+  before the call.)  Flushing may degrade compression for some compression
+  algorithms and so it should be used only when necessary.
+
+    If flush is set to Z_FULL_FLUSH, all output is flushed as with
+  Z_SYNC_FLUSH, and the compression state is reset so that decompression can
+  restart from this point if previous compressed data has been damaged or if
+  random access is desired. Using Z_FULL_FLUSH too often can seriously degrade
+  the compression.
+
+    If deflate returns with avail_out == 0, this function must be called again
+  with the same value of the flush parameter and more output space (updated
+  avail_out), until the flush is complete (deflate returns with non-zero
+  avail_out).
+
+    If the parameter flush is set to Z_FINISH, pending input is processed,
+  pending output is flushed and deflate returns with Z_STREAM_END if there
+  was enough output space; if deflate returns with Z_OK, this function must be
+  called again with Z_FINISH and more output space (updated avail_out) but no
+  more input data, until it returns with Z_STREAM_END or an error. After
+  deflate has returned Z_STREAM_END, the only possible operations on the
+  stream are deflateReset or deflateEnd.
+  
+    Z_FINISH can be used immediately after deflateInit if all the compression
+  is to be done in a single step. In this case, avail_out must be at least
+  0.1% larger than avail_in plus 12 bytes.  If deflate does not return
+  Z_STREAM_END, then it must be called again as described above.
+
+    deflate() sets strm->adler to the adler32 checksum of all input read
+  so far (that is, total_in bytes).
+
+    deflate() may update data_type if it can make a good guess about
+  the input data type (Z_ASCII or Z_BINARY). In doubt, the data is considered
+  binary. This field is only for information purposes and does not affect
+  the compression algorithm in any manner.
+
+    deflate() returns Z_OK if some progress has been made (more input
+  processed or more output produced), Z_STREAM_END if all input has been
+  consumed and all output has been produced (only when flush is set to
+  Z_FINISH), Z_STREAM_ERROR if the stream state was inconsistent (for example

+    about the flush parameter).
+
+  Before the call of inflate(), the application should ensure that at least

+
+    If the parameter flush is set to Z_SYNC_FLUSH, inflate flushes as much
+  output as possible to the output buffer. The flushing behavior of inflate is
+  not specified for values of the flush parameter other than Z_SYNC_FLUSH
+  and Z_FINISH, but the current implementation actually flushes as much output
+  as possible anyway.
+
+    inflate() should normally be called until it returns Z_STREAM_END or an
+  error. However if all decompression is to be performed in a single step
+  (a single call of inflate), the parameter flush should be set to
+  Z_FINISH. In this case all pending input is processed and all pending
+  output is flushed; avail_out must be large enough to hold all the
+  uncompressed data. (The size of the uncompressed data may have been saved
+  by the compressor for this purpose.) The next operation on this stream must
+  be inflateEnd to deallocate the decompression state. The use of Z_FINISH
+  is never required, but can be used to inform inflate that a faster routine
+  may be used for the single inflate() call.
+
+     If a preset dictionary is needed at this point (see inflateSetDictionary
+  below), inflate sets strm-adler to the adler32 checksum of the
+  dictionary chosen by the compressor and returns Z_NEED_DICT; otherwise 
+  it sets strm->adler to the adler32 checksum of all output produced
+  so far (that is, total_out bytes) and returns Z_OK, Z_STREAM_END or

+  checks that its computed adler32 checksum is equal to that saved by the

+
+     The windowBits parameter is the base two logarithm of the window size
+   (the size of the history buffer).  It should be in the range 8..15 for this

+
+     The memLevel parameter specifies how much memory should be allocated
+   for the internal compression state. memLevel=1 uses minimum memory but
+   is slow and reduces compression ratio; memLevel=9 uses maximum memory

+   string match).  Filtered data consists mostly of small values with a
+   somewhat random distribution. In this case, the compression algorithm is
+   tuned to compress them better. The effect of Z_FILTERED is to force more
+   Huffman coding and less string matching; it is somewhat intermediate

-  Generate a table for a byte-wise 32-bit CRC calculation on the polynomial:
-  x^32+x^26+x^23+x^22+x^16+x^12+x^11+x^10+x^8+x^7+x^5+x^4+x^2+x+1.
-
-  Polynomials over GF(2) are represented in binary, one bit per coefficient,
-  with the lowest powers in the most significant bit.  Then adding polynomials
-  is just exclusive-or, and multiplying a polynomial by x is a right shift by
-  one.  If we call the above polynomial p, and represent a byte as the
-  polynomial q, also with the lowest power in the most significant bit (so the
-  byte 0xb1 is the polynomial x^7+x^3+x+1), then the CRC is (q*x^32) mod p,
-  where a mod b means the remainder after dividing a by b.
-
-  This calculation is done using the shift-register method of multiplying and
-  taking the remainder.  The register is initialized to zero, and for each
-  incoming bit, x^32 is added mod p to the register if the bit is a one (where
-  x^32 mod p is p+x^32 = x^26+...+1), and the register is multiplied mod p by
-  x (which is shifting right by one and adding x^32 mod p if the bit shifted
-  out is a one).  We start with the highest power (least significant bit) of
-  q and repeat for all eight bits of q.
-
-  The table is simply the CRC of all possible eight bit values.  This is all
-  the information needed to generate CRC's on data a byte at a time for all
-  combinations of CRC register values and incoming bytes.

-/*
- *  ALGORITHM
- *
- *      The "deflation" process depends on being able to identify portions
- *      of the input text which are identical to earlier input (within a
- *      sliding window trailing behind the input currently being processed).
- *
- *      The most straightforward technique turns out to be the fastest for
- *      most input files: try all possible matches and select the longest.
- *      The key feature of this algorithm is that insertions into the string
- *      dictionary are very simple and thus fast, and deletions are avoided
- *      completely. Insertions are performed at each input character, whereas
- *      string matches are performed only when the previous match ends. So it
- *      is preferable to spend more time in matches to allow very fast string
- *      insertions and avoid deletions. The matching algorithm for small
- *      strings is inspired from that of Rabin & Karp. A brute force approach
- *      is used to find longer strings when a small match has been found.
- *      A similar algorithm is used in comic (by Jan-Mark Wams) and freeze
- *      (by Leonid Broukhis).
- *         A previous version of this file used a more sophisticated algorithm
- *      (by Fiala and Greene) which is guaranteed to run in linear amortized
- *      time, but has a larger average cost, uses more memory and is patented.
- *      However the F&G algorithm may be faster for some highly redundant
- *      files if the parameter max_chain_length (described below) is too large.
- *
- *  ACKNOWLEDGEMENTS
- *
- *      The idea of lazy evaluation of matches is due to Jan-Mark Wams, and
- *      I found it in 'freeze' written by Leonid Broukhis.
- *      Thanks to many people for bug reports and testing.

+/*
+ *  ALGORITHM
+ *
+ *      The "deflation" process depends on being able to identify portions
+ *      of the input text which are identical to earlier input (within a
+ *      sliding window trailing behind the input currently being processed).
+ *
+ *      The most straightforward technique turns out to be the fastest for
+ *      most input files: try all possible matches and select the longest.
+ *      The key feature of this algorithm is that insertions into the string
+ *      dictionary are very simple and thus fast, and deletions are avoided
+ *      completely. Insertions are performed at each input character, whereas
+ *      string matches are performed only when the previous match ends. So it
+ *      is preferable to spend more time in matches to allow very fast string
+ *      insertions and avoid deletions. The matching algorithm for small
+ *      strings is inspired from that of Rabin & Karp. A brute force approach
+ *      is used to find longer strings when a small match has been found.
+ *      A similar algorithm is used in comic (by Jan-Mark Wams) and freeze
+ *      (by Leonid Broukhis).
+ *         A previous version of this file used a more sophisticated algorithm
+ *      (by Fiala and Greene) which is guaranteed to run in linear amortized

-   Notes beyond the 1.93a appnote.txt:
-
-   1. Distance pointers never point before the beginning of the output
-      stream.
-   2. Distance pointers can point back across blocks, up to 32k away.
-   3. There is an implied maximum of 7 bits for the bit length table and
-      15 bits for the actual data.
-   4. If only one code exists, then it is encoded using one bit.  (Zero
-      would be more efficient, but perhaps a little confusing.)  If two
-      codes exist, they are coded using one bit each (0 and 1).
-   5. There is no way of sending zero distance codes--a dummy must be
-      sent if there are none.  (History: a pre 2.0 version of PKZIP would
-      store blocks with no distance codes, but this was discovered to be
-      too harsh a criterion.)  Valid only for 1.93a.  2.04c does allow
-      zero distance codes, which is sent as one code of zero bits in
-      length.
-   6. There are up to 286 literal/length codes.  Code 256 represents the
-      end-of-block.  Note however that the static length tree defines
-      288 codes just to fill out the Huffman codes.  Codes 286 and 287
-      cannot be used though, since there is no length base or extra bits
-      defined for them.  Similarily, there are up to 30 distance codes.
-      However, static trees define 32 codes (all 5 bits) to fill out the
-      Huffman codes, but the last two had better not show up in the data.
-   7. Unzip can check dynamic Huffman blocks for complete code sets.
-      The exception is that a single code would not be complete (see #4).
-   8. The five bits following the block type is really the number of
-      literal codes sent minus 257.
-   9. Length codes 8,16,16 are interpreted as 13 length codes of 8 bits
-      (1+6+6).  Therefore, to output three times the length, you output
-      three codes (1+1+1), whereas to output four times the same length,
-      you only need two codes (1+3).  Hmm.
-  10. In the tree reconstruction algorithm, Code = Code + Increment
-      only if BitLength(i) is not zero.  (Pretty obvious.)
-  11. Correction: 4 Bits: # of Bit Length codes - 4     (4 - 19)
-  12. Note: length code 284 can represent 227-258, but length code 285
-      really is 258.  The last length deserves its own, short code
-      since it gets used a lot in very redundant files.  The length
-      258 is special since 258 - 3 (the min match length) is 255.
-  13. The literal/length and distance code bit lengths are read as a
-      single stream of lengths.  It is possible (and advantageous) for
-      a repeat code (16, 17, or 18) to go across the boundary between
-      the two sets of lengths.

+   Notes beyond the 1.93a appnote.txt:
+
+   1. Distance pointers never point before the beginning of the output
+      stream.
+   2. Distance pointers can point back across blocks, up to 32k away.
+   3. There is an implied maximum of 7 bits for the bit length table and
+      15 bits for the actual data.
+   4. If only one code exists, then it is encoded using one bit.  (Zero
+      would be more efficient, but perhaps a little confusing.)  If two
+      codes exist, they are coded using one bit each (0 and 1).
+   5. There is no way of sending zero distance codes--a dummy must be
+      sent if there are none.  (History: a pre 2.0 version of PKZIP would
+      store blocks with no distance codes, but this was discovered to be
+      too harsh a criterion.)  Valid only for 1.93a.  2.04c does allow
+      zero distance codes, which is sent as one code of zero bits in
+      length.
+   6. There are up to 286 literal/length codes.  Code 256 represents the
+      end-of-block.  Note however that the static length tree defines
+      288 codes just to fill out the Huffman codes.  Codes 286 and 287
+      cannot be used though, since there is no length base or extra bits
+      defined for them.  Similarily, there are up to 30 distance codes.
+      However, static trees define 32 codes (all 5 bits) to fill out the
+      Huffman codes, but the last two had better not show up in the data.
+   7. Unzip can check dynamic Huffman blocks for complete code sets.
+      The exception is that a single code would not be complete (see #4).
+   8. The five bits following the block type is really the number of
+      literal codes sent minus 257.
+   9. Length codes 8,16,16 are interpreted as 13 length codes of 8 bits
+      (1+6+6).  Therefore, to output three times the length, you output
+      three codes (1+1+1), whereas to output four times the same length,
+      you only need two codes (1+3).  Hmm.
+  10. In the tree reconstruction algorithm, Code = Code + Increment
+      only if BitLength(i) is not zero.  (Pretty obvious.)
+  11. Correction: 4 Bits: # of Bit Length codes - 4     (4 - 19)
+  12. Note: length code 284 can represent 227-258, but length code 285
+      really is 258.  The last length deserves its own, short code
+      since it gets used a lot in very redundant files.  The length
+      258 is special since 258 - 3 (the min match length) is 255.
+  13. The literal/length and distance code bit lengths are read as a
+      single stream of lengths.  It is possible (and advantageous) for
+      a repeat code (16, 17, or 18) to go across the boundary between
+      the two sets of lengths.

-   Huffman code decoding is performed using a multi-level table lookup.
-   The fastest way to decode is to simply build a lookup table whose
-   size is determined by the longest code.  However, the time it takes
-   to build this table can also be a factor if the data being decoded
-   is not very long.  The most common codes are necessarily the
-   shortest codes, so those codes dominate the decoding time, and hence
-   the speed.  The idea is you can have a shorter table that decodes the
-   shorter, more probable codes, and then point to subsidiary tables for
-   the longer codes.  The time it costs to decode the longer codes is
-   then traded against the time it takes to make longer tables.
-
-   This results of this trade are in the variables lbits and dbits
-   below.  lbits is the number of bits the first level table for literal/
-   length codes can decode in one step, and dbits is the same thing for
-   the distance codes.  Subsequent tables are also less than or equal to
-   those sizes.  These values may be adjusted either when all of the
-   codes are shorter than that, in which case the longest code length in
-   bits is used, or when the shortest code is *longer* than the requested
-   table size, in which case the length of the shortest code in bits is
-   used.
-
-   There are two different values for the two tables, since they code a
-   different number of possibilities each.  The literal/length table
-   codes 286 possible values, or in a flat code, a little over eight
-   bits.  The distance table codes 30 possible values, or a little less
-   than five bits, flat.  The optimum values for speed end up being
-   about one bit more than those, so lbits is 8+1 and dbits is 5+1.
-   The optimum values may differ though from machine to machine, and
-   possibly even between compilers.  Your mileage may vary.

+   Huffman code decoding is performed using a multi-level table lookup.
+   The fastest way to decode is to simply build a lookup table whose
+   size is determined by the longest code.  However, the time it takes
+   to build this table can also be a factor if the data being decoded
+   is not very long.  The most common codes are necessarily the
+   shortest codes, so those codes dominate the decoding time, and hence
+   the speed.  The idea is you can have a shorter table that decodes the
+   shorter, more probable codes, and then point to subsidiary tables for
+   the longer codes.  The time it costs to decode the longer codes is
+   then traded against the time it takes to make longer tables.
+
+   This results of this trade are in the variables lbits and dbits
+   below.  lbits is the number of bits the first level table for literal/
+   length codes can decode in one step, and dbits is the same thing for
+   the distance codes.  Subsequent tables are also less than or equal to
+   those sizes.  These values may be adjusted either when all of the
+   codes are shorter than that, in which case the longest code length in
+   bits is used, or when the shortest code is *longer* than the requested
+   table size, in which case the length of the shortest code in bits is
+   used.
+
+   There are two different values for the two tables, since they code a
+   different number of possibilities each.  The literal/length table
+   codes 286 possible values, or in a flat code, a little over eight
+   bits.  The distance table codes 30 possible values, or a little less
+   than five bits, flat.  The optimum values for speed end up being
+   about one bit more than those, so lbits is 8+1 and dbits is 5+1.
+   The optimum values may differ though from machine to machine, and
+   possibly even between compilers.  Your mileage may vary.
