Flex is a tool for generating scanners. A scanner, sometimes called a
tokenizer, is a program which recognizes lexical patterns in text. The
flex program reads user-specified input files, or its standard input
if no file names are given, for a description of a scanner to generate.
The description is in the form of pairs of regular expressions and C
code, called rules. Flex generates a C source file named, "lex.yy.c",
which defines the function yylex(). The file "lex.yy.c" can be compiled
and linked to produce an executable. When the executable is run, it
analyzes its input for occurrences of text matching the regular
expressions for each rule. Whenever it finds a match, it executes the
corresponding C code.
===> The following configuration options are available for flex-2.6.4_3:
DOCS=on: Build and/or install documentation
EXAMPLES=on: Build and/or install examples
NLS=on: Native Language Support
===> Use 'make config' to modify these settings
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.
Approved by: portmgr (tcberner)
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.

Install texinfo files (GNU info) into ${PREFIX}/share/info
After a discussion on the mailing list on moving manpages to
${PREFIX}/share/man for consistency with base where it is
installed in usr/share/man, it appeared the same should happen
to GNU info files which were installed under share in base and
not in ports.
Now texinfo is not in base on any of the supported version of FreeBSD
it is possible to proceed to this move and it is easier to do than
the manpage change.
Other benefit than consistency are less patching: all build tools but
cmake are expecting info files to be under share/info and cmake (patched here)
was having an exception for BSD so the patch makes FreeBSD case less
specific for them

Convert USE_BISON to USES= bison
It brings bison as a build dependency in case it is set the following way:
USES= bison or USES= bison:build
it brings bison as a run dependency in case it is set the following way:
USES= bison:run
it brings bison both as a run and build dependency in case it the set the
following way:
USES= bison:both
While here trim some headers
Convert some USE_GNOME= gnomehack to USES= pathfix

Note that there's flex 2.5.4 in the base system. This port provides
a newer version for programs that require it, textproc/xxdiff for one.
