- This directory contains the GNU regex library. It is compliant with
- POSIX.2, except for internationalization features.
-
- See the file NEWS for a list of major changes in the current release.
-
- See the file INSTALL for compilation and installation instructions.
- (The only thing installed is the documentation; regex.c is compiled into
- regex.o, but not installed anywhere.)
-
- The subdirectory `doc' contains a (programmers') manual for the library.
- It's probably out-of-date. Improvements are welcome.
-
- The subdirectory `test' contains the various tests we've written.
-
- We know this code is not as fast as it might be. If you have specific
- suggestions, profiling results, or other such useful information to
- report, please do.
-
- Emacs 18 is not going use this revised regex (but Emacs 19 will). If
- you want to try it with Emacs 18, apply the patch at the end of this
- file first.
-
- Mail bug reports to bug-gnu-utils@prep.ai.mit.edu.
-
- Please include an actual regular expression that fails (and the syntax
- used to compile it); without that, there's no way to reproduce the bug,
- so there's no way we can fix it. Even if you include a patch, also
- include the regular expression in error; otherwise, we can't know for
- sure what you're trying to fix.
-
- Here is the patch to make this version of regex work with Emacs 18.
