Subject: do not use sed for version date processing but rather cut and tr
X-Git-Url: http://git.megacz.com/?a=commitdiff_plain;h=3c287486b41b5f99b20f700a61f5897940403aaf;hp=-c;p=ghc-hetmet.git

do not use sed for version date processing but rather cut and tr

Based on an idea from Karel Gardas, who had troubles with the original
sed version (which didn't work with /usr/bin/sed on Solaris).
