Subject: v15i064: A window manager for X, Part01/04 Newsgroups: comp.sources.unix Sender: sources Approved: rsalz@uunet.UU.NET Submitted-by: Tom LaStrange <esunix!tlastran> Posting-number: Volume 15, Issue 64 Archive-name: twm/part01 Here is my first source posting to comp.unix.sources. I hope this is the appropriate place for this code. There are 3 shar files for "twm". Twm is a window manager for X11. Twm has never been compiled or run on a System V machine. All development was done on a Sun 3 running Release 3.4 of the operating system. It has also been run on a VaxStation II and a VaxStation 8000. Nothing real special you should have to do to compile it. If you are running X11R1, you will have to link in the resource manager library in addition to libX11.a. We here at E&S have been using twm for almost 6 months now in various states of development. I hope you find it to be useful tool. Twm is my first, and so far, only X program. If I'm doing anything blatently wrong, forgive me. I would appreciate hearing from those who like it as well as those who dislike it. -- Tom LaStrange Evans & Sutherland Computer Corporation UUCP Address: {ihnp4,seismo}!utah-cs!utah-gr!uplherc!esunix!tlastran Alternate: {ihnp4,decvax}!decwrl!esunix!tlastran ------------------------------------------- #! /bin/sh # This is a shell archive, meaning: # 1.
