John E. Davis Software

I have been involved in the free/open software movement for many years, long before it was fashionable. I have no strong philosophical or religious feelings about open software; my view is purely pragmatic: Since I take from the open source community, I try to give back to it.

Some of my contributions to the open software world include:

• jed, a scriptable, multi-platform text editor.
• S-Lang, a programmer's library that includes an array-based scripting language with a C-like syntax.
• slrn, a powerful threaded newsreader for Unix, VMS, OS/2, and Win32 systems.
• most, a more/less style paging program that supports multiple windows and scrolls left/right.
