Revision history for Perl extension Parse::RecDescent.

1.00  Mon Aug 11 13:17:13 1997

	- original version


1.01  Mon Sep  8 18:04:14 EST 1997

	- changed "quotemeta" to "quotemeta $_" in Text::Balanced
	  to workaround bug in Perl 5.002 and 5.003


1.10  Tue Sep 30 14:51:49 EST 1997

	- fixed fatal bug in tracing code

	- added m<delim>...<delim> format for regex tokens

	- added support for trailing modifiers (/.../gimsox) in regex tokens

	- added $thisline variable


1.20  Thu Oct  2 11:46:57 EST 1997

	- fixed handling of trailing regex modifiers (now no whitespace allowed
	  before between last delimiter and first modifier)

	- added trace diagnostic for failure/success of actions
	  (demystifies failures caused by an action returning undef)

	- added context for "Matched rule..." trace

        - added a test so that an integer value (N>1) in the
          $::RD_TRACE variable now truncates (to N characters) all
          contexts reported in any trace

	- added "start-up" actions: actions appearing before the first rule
          were previously an error. They are now executed (once) at
          the start of the parser's namespace.


1.21  Sat Oct  4 17:12:23 EST 1997

	- modified truncation of context in trace diagnostics (successful
	  matches now report first N/2 and last N/2 chars, instead of first N)

	- fixed incorrect version number in Balanced.pm


1.22  Tue Oct  7 11:53:27 EST 1997

	- fixed lurking trace problem with certain pathological regexes

	- fixed bug in generation of special namespaces (this was serious
	  as it prevented the use of more than one alternation in a parser,
	  as well as preventing the use of more than one parser in a script!
