Usage: instcmds [options] ARGS

Extract (un-)installation commands from the Makefile.
This script may only be interesting to maintainers and
requires GNU make.

The options are
  --help            show this message
  --install         Show the install commands (default)
  --type=TYPE       One of "pre", "normal" (default), and "post"
  --uninstall       Show the uninstall commands
  --version         show the version information

The ARGS are passed directly to the make command.

Please report bugs to <voss@seehuhn.de>.
