$this runs all necessary programs to build a configure script. It can
also run the configure script, make, and install the program. If you are not a
developer, follow the instrutions in INSTALL instead of using $this.

Use  $this             to create the configure script
Use  $this --all       to build and install with default settings
Use  $this --clear     to delete all files generated by the autotools
Use  $this --fast ...  if configure need not be rebuilt

--builddir specifies where compilation should occur [default=$builddir]"
