Revision:	1.9
Committed:	Sat Jul 26 11:03:59 2003 UTC (20 years, 10 months ago) by elmex
Content type:	application/xml
Branch:	MAIN
Changes since 1.8:	+178 -78 lines
Log Message:	Wrote enc- and decoding functions in haskell, to do the basic stuff with Word8's. Please check for endianess. The haskell code might not compile, but it should work with some fixes. enc_pass* and enc_string* might not be correctly implemented, please check.
