pkgtasks is a shell script library to ease writing POSIX-compliant
shell scripts to handle common tasks during installation or removal
of a package, e.g.,
* creating groups and users needed by the package
* creating and removing directories with special permissions and
ownership,
* copying example config files to their final locations during
package installation, and removing them during package removal
if they don't differ from the example ones,
* reminding the user of files that may be customized after
package installation.
