Back in the day, the Ardent Window Manager - awm - was the red hot cutting edge of innovation. Now, you can run it on Solaris.
My modified source code is
available. See the file README-PCT for the relatively
minimal changes I had to make.
I've built awm for Solaris and made the packages available.
Choose the right file from the following list:
To install,
pkgadd -d PCTawm.i386.pkg PCTawm
where you should replace "PCTawm.i386.pkg" with whichever file you downloaded.
(Using pkgadd should work on OpenSolaris distributions too. You can safely ignore any conflicts marked as "attribute change only". And binary compatibility should ensure that the software works correctly as well.)
