+ * NAME
+ * simplestring
+ * AUTHOR
+ * Dan Libby, aka danda (dan@libby.com)
+ * CREATION DATE
+ * 06/2000
+ * HISTORY
+ * $Log: simplestring.c,v $
+ * Revision 1.4 2003/12/16 21:00:21 sniper
+ * Fix some compile warnings (patch by Joe Orton)
+ *
+ * Revision 1.3 2002/08/22 01:25:50 sniper
+ * kill some compile warnings
+ *
+ * Revision 1.2 2002/07/05 04:43:53 danda
+ * merged in updates from SF project. bring php repository up to date with xmlrpc-epi version 0.51
+ *
+ * Revision 1.4 2002/02/13 20:58:50 danda
+ * patch to make source more windows friendly, contributed by Jeff Lawson
+ *
+ * Revision 1.3 2001/09/29 21:58:05 danda
+ * adding cvs log to history section
+ *
+ * 10/15/2000 -- danda -- adding robodoc documentation
+ * PORTABILITY
+ * Coded on RedHat Linux 6.2. Builds on Solaris x86. Should build on just
+ * about anything with minor mods.
+ * NOTES
+ * This code was written primarily for xmlrpc, but has found some other uses.
+ *
+ * simplestring is, as the name implies, a simple API for dealing with C strings.
+ * Why would I write yet another string API? Because I couldn't find any that were
+ * a) free / GPL, b) simple/lightweight, c) fast, not doing unneccesary strlens all
+ * over the place. So. It is simple, and it seems to work, and it is pretty fast.
+ *
+ * Oh, and it is also binary safe, ie it can handle strings with embedded NULLs,
+ * so long as the real length is passed in.
+ *
+ * And the masses rejoiced.
+ *
+ * BUGS
+ * there must be some.
