The first version of a script that allows building rpm packages directly from
CVS.  It currently works for ghc only, but will be extended to cover the
other fptools.

It should work on all rpm-based systems, as I tried to avoid any dependency on
Red Hat systems (as far as I am aware of them).  In particular, the rpm build
process is carried out below /tmp instead of the standard /usr/src/redhat
hierarchy.

By default the cvs head of the anonymous repository is built, but cvs-style -d
-D, and -r options allow to built from a different repository and revision.

[This version is only half tested, because the CVS head seems to not build
anymore today.]

+
+# Usage
+# -----
+#
+# This script checks the given version of an fptools component out of CVS and
+# builds a binary rpm package from it.  By default it builds the CVS head from
+# anonymous CVS.  In the case of anonymous CVS, this script requires that `cvs 
+# login' was already executed.
+#
+# The current version of this script handles ghc only, but in fact it is 
+# planned to extend it to cover the other components in fptools.
+#
+# Options:
+#
+# -d REPOSITORY -- Value passed to CVS's -d option
+# -r TAG	-- build the revision identified by the given CVS tag
+# -D DATE	-- build the revision identified by the given CVS date
+#
+# (if there is more than one of the options -r and -D, the last one takes 
+# effect)
+
+# Requires: autoconf, cvs, GNU tar, gnuopt
+
+# Default values
