+This directory conains a version of LibPCRE 4.3 that has been stripped
+down to under half its original uncompressed size.  So if you want
+docs, tests and such, you should go to the PCRE website at
+http://www.pcre.org .  Here are the changes for the Nmap version:
+
+o rm -rf doc testdata pcretest.c pcregrep.c pcredemo.c ChangeLog
+
+o Renamed configure.in to configure.ac
+
+o Removed Runtest, Runtest.in
+
+o Removed pcretest and pcregrep from the Makefile.in all target:
+
+--- Makefile.in.old     Sun Jul 20 23:00:56 2003
++++ Makefile.in Sun Jul 20 23:01:13 2003

+o Stripped down Makefile and configure.ac substantially to remove
+  libtool dependency (was having trouble on Mac OS X), remove Windows
+  stuff (Nmap uses a custom MS VC project for this), and insure it only
+  worries about building libpcre.a (which is now build in the libpcre
+  directory rather than in libpcre/.libs ).
+
+
+o Regenerated configure script by running 'aclocal; autoconf'
