The Lemon program is an LALR(1) parser generator. It takes a context free
grammar and converts it into a subroutine that will parse a file using that
grammar.
Lemon is similar to much more famous programs Yacc and Bison. But lemon is
not compatible with either of them; there are several important differences:
- Lemon using a different grammar syntax which is less prone to
programming errors
- Lemon generates a parser that is faster than Yacc or Bison parsers
(according to the author)
- The parser generated by Lemon is both re-entrant and thread-safe
- Lemon includes the concept of a non-terminal destructor, which makes
it much easier to write a parser that does not leak memory
Remove WWW entries moved into port Makefiles
Commit b7f05445c00f has added WWW entries to port Makefiles based on
WWW: lines in pkg-descr files.
This commit removes the WWW: lines of moved-over URLs from these
pkg-descr files.

Add WWW entries to port Makefiles
It has been common practice to have one or more URLs at the end of the
ports' pkg-descr files, one per line and prefixed with "WWW:". These
URLs should point at a project website or other relevant resources.
Access to these URLs required processing of the pkg-descr files, and
they have often become stale over time. If more than one such URL was
present in a pkg-descr file, only the first one was tarnsfered into
the port INDEX, but for many ports only the last line did contain the
port specific URL to further information.
There have been several proposals to make a project URL available as
a macro in the ports' Makefiles, over time.

Hrm... NO_MAN isn't supported in 4.X. Use NOMAN for now even though it
incurs a warning on 6.X: at least it compiles now.

Update lemon to the latest version in the SQLite repo. Please let me know
if there are any grammar problems with this newer version. Assume
maintainership.
Approved by: maintainer
Switch from the no-longer-supported-by-gcc varargs.h to stdarg.h. The
sqlite itself switched in May, apparently. databases/libgda needs to
switch too, or, better yet, use the sqlite port instead of building its
own.
