# Implement a uniform 'install' syntax independent of which of the two
# "standard" install programs is installed. Based on ideas in, but not
# copied from, the GNU fileutils install-sh script. Usage:
# instcopy -c [-m <mode>] <srcfile> (<dstdir>|<dstfile>)
doit=""
# Uncomment the following line for testing
#doit="echo "
mode=""
