Rx is found in the files `rx.h' and `rx.c'. It is an upward
compatable replacement for GNU regex. If you want to try GNU Rx in
your own application, the documentation for GNU _regex_ will tell you
how.
Notes:
* This release of Rx is not quite ready for use in GNU Emacs.
* When initializing a variable of type `struct re_pattern_buf',
use `bzero' or an equivelent function first. Some older code
might try to work by assigning 0 to specific fields defined in
GNU regex. All of those fields still exist, but new fields have
been added (and more may be in the future).
* Rx keeps a cache of information about patterns. The size of this
cache may effect performance. The default size should be large
enough for most applications. However, for a program like `sed',
there is no reason to keep the cache small. Such programs want to
assign as large a number as possible without thrashing (see main in
sed.c for example).
