portable shell tool from the GNU project
GNU shtool is a tool for developers of software programs. It is a
compilation of small but very stable and portable shell scripts into
a single shell tool. All ingredients were in successful use over many
years in various free software projects. The compiled shtool program
is intended to be used inside the source tree of other free software
packages. There it can overtake various (usually non-portable) tasks
related to the building and installation of such a package. It
especially can replace the old mkdir.sh, install.sh and related
scripts.
