[ANN] lrexlib 2.7.2 released

[rrt@...]

I am happy to announce the release of lrexlib 2.7.2,
Lua binding for regex libraries.

  * Fixed the use of alternative allocators, and a memory leak.
  * Simplify the build system further.
  * Change rockspec to build from git now that github no longer
    supports downloads.

Install it as luarock lrexlib-gnu-2.7.2, lrexlib-oniguruma-2.7.2,
lrexlib-pcre-2.7.2, lrexlib-posix-2.7.2, lrexlib-tre-2.7.2 (see
http://luarocks.org/repositories/rocks )
