# Shell script for doing installs.
# The old bsd install did pretty much what we want, but the SYSV install
# doesn't.  Hence this shell script which does what we need.
# 
# Usage:  ttinstall <version> <dest-dir> file...
# 
# ttinstall will create dest-dir if needed and copy each named file
# to that directory.  If a file's name ends in .so.[0-9] or .so.[0-9][0-9],
# a symlink is created in the destination directory without the version.
# (This breaks if any shared library has a version over 99, but I'm not
# worried.)
# If the file is ELF (binary or shared library), then mcs is used to
# strip the comment and replace it with a short one containing
# the version.
