Usage:
sh doc/manpages.sh -i|-u -p MANDIR FILE...
sh doc/manpages.sh -h
EOF
}
help() {
cat <<-'EOF'
Options:
-i set ACTION=install
-u set ACTION=uninstall
-p MANDIR use $MANDIR as the prefix directory
-h, --help show this message
Installs/uninstalls manpage files into MANDIR using the original
filename as a hint towards which subdirectory to pick: the
`prog.ru.1` file is installed under the `man1/` directory
hierarchy under the `ru/` language folder. When then language
is `en`, a the toplevel `man1/` gets a symlink to the `en/`
language folder:
man/
en/
man1/
prog.1
ru/
man1/
prog.1
man1/
prog.1 -> ../en/man1/prog.1
Examples:
Install prog.en.1 under `/usr/man`:
$ sh doc/manpages.sh -ip/usr/man prog.en.1
Uninstall all files listed under doc/ from `$PREFIX`:
sh doc/manpages.sh -up "$PREFIX" doc/*.[0-9]
