Starting with version 7.5 of Tcl, the package facility (see package
manual page) became available. Instructions on how to make a stooop
package follow.

First, you must install stooop version 3.5 or above as a package. If
you do not have the stooop extension yet, get it from
http://www.mygale.org/~jfontain/,
ftp://ftp.neosoft.com/pub/tcl/incoming/ or
ftp://ftp.neosoft.com/pub/tcl/sorted/devel/

Once the stooop package is working and installed, you are ready to
install scwoop as a package. Choose a directory where the package
should be installed (for example /usr/local/lib/scwoop, but you may
choose another: look at the pkg_mkIndex manual page for more
information (well look at it any case :-)).

Now type:

$ mkdir /usr/local/lib/scwoop
$ instapkg.tcl /usr/local/lib/scwoop

To test if it works:

$ cd ..
$ wish scwoop-2.2/demo.tcl

should successfully launch the scwoop demonstration application.
