frag-opt 0.5.5

frag-opt is a re-entrant, portable command-line parsing library. To see how you can use this in your program, take a look at doc/example.c or take a look at the man-page ("man frag-opt") once youve installed.
The man-page talks about an info-page, but as its still incomplete, I decided not to include it with the distribution yet.
Installation:
./configure (the standard options work here, nothing frag-opt specific)
make
make check (optional)
make install (become root if necessary)
Should compile on any ANSI C compiler. Should compile on C++ compilers too (at least does with g++).
Enhancements:
- FRAG_POSIX works (I think)
- large amounts of different options for one option are now printed better
- removed some obsolete stuff from the header-file
- some additions and fixes to the man-page
- the term cluster is now deprecated. group is used instead.
- added a healthy dose of consts (thanks to chisel)
- changed the help-message format a little
- tuned the wrapping-algorithm
- added -D_REENTRANT to build-flags to make the library magically better (unless Im mistaken, theres something in (g)libc that requires this to make it re-entrant)
