LPeg is a new pattern-matching library for Lua, based on Parsing Expression
Grammars (PEGs).
Following the Snobol tradition, LPeg defines patterns as first-class objects.
That is, patterns are regular Lua values (represented by userdata). The library
offers several functions to create and compose patterns. With the use of
metamethods, several of these functions are provided as infix or prefix
operators. On the one hand, the result is usually much more verbose than the
typical encoding of patterns using the so called regular expressions (which
typically are not regular expressions in the formal sense). On the other hand,
first-class patterns allow much better documentation (as it is easy to comment
the code, to break complex definitions in smaller parts, etc.) and are
extensible, as we can define new functions to create and compose patterns.
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.

USES=lua gained flavors.
Ports using USES=lua:module or lua:flavors will be flavored. A range of
supported lua versions can be set using XX-YY (or XX-, or -YY, or simply ZZ)
for ports not supporting all lua versions.
USES=lua sets LUA_FLAVOR that needs to be used on all dependencies of
flavored lua ports, in a similar way as PHP or Python flavors.
