+ /* a Postscript-like interpreter) but rather to perform simple pattern */
+ /* matching. */

+ /* ... /Field <data> ... */
+ /* */
+ /* where <data> can be a number, a boolean, a string, or an array of */
+ /* numbers. There are a few exceptions, namely the encoding, font name, */
+ /* charstrings, and subrs; they are handled with a special pattern */
+ /* matching routine. */
+ /* */
+ /* All other common cases are handled very simply. The matching rules */
+ /* are defined in the file `t1tokens.h' through the use of several */

+ /* */
+ /* The function `parse_dict' simply scans *linearly* a given dictionary */
+ /* (either the top-level or private one) and calls the appropriate */
+ /* callback when it encounters an immediate keyword. */
+ /* */
+ /* This is by far the fastest way one can find to parse and read all */
+ /* data. */
+ /* */
+ /* This led to tremendous code size reduction. Note that later, the */
