[pcre-dev] Caching and PCRE

Hi All
I ask to make sure that I am not missing something!

Does PCRE provide caching for the compiled (or original) Regular Expression or does it assume that the user would provide such functionality.  I did not find anything in the man pages except of some note about caching C compiler usage in build time which has nothing to do with my question.

I need to know for sure before I considering developing such a functionality myself.
