%description
Rx is, among other things, an implementation of the interface
specified by POSIX for programming with regular expressions.  Some
other implementations are GNU regex.c and Henry Spencer's regex
library.

The library is available as 32-bit and 64-bit.

%description devel
Rx is, among other things, an implementation of the interface
specified by POSIX for programming with regular expressions.  Some
other implementations are GNU regex.c and Henry Spencer's regex
library.

This package contains files needed for development with librx.

If you are compiling a 32-bit program, no special compiler options are
needed.

If you are compiling a 64-bit program, you have to compile and link your
application with "cc -q64" or "gcc -maix64".
