Committed:	Wed May 29 19:41:59 2002 UTC (22 years, 6 months ago) by tdb

Changes since 1.7:	+6 -2 lines
Log Message:	This ihost now uses autoconf and automake to make a "normal" installation and distribution ;) It's now far easier to compile. To build from CVS :- aclocal autoheader autoconf automake -a -c Then for compiling (end users will only need to do this) :- ./configure make make install To build a distribution :- make dist
