blt8.0-unoff is a blt version compatible with tk8.0 based on blt2.1. from the blt README:
There's a story behind these "unofficial" releases of BLT: shortly after George released BLT 2.1 back in April '96, he "disappeared from the scene", i.e. he didn't show up in comp.lang.tcl anymore, and he also didn't release updates of BLT. Newer releases of Tcl/Tk (7.5/4.1-8.0) broke BLT 2.1, and while Tcl/Tk went multi-platform (Unix, Win32(s), MacOS), BLT was still restricted to Unix/X11. Of course, there were also some bugs in 2.1. Due to BLT's popularity, and because its sources are freely available, several people posted patches which fixed bugs, made BLT compatible with newer versions of Tcl/Tk, and even made it compile under Win32. Unfortunately, these efforts were not coordinated, and therefore some patches clashed with others. To address this less than desirable situation, I've offered (end of February '97) to coordinate the efforts to keep BLT up to date. Since then, I've released several "unofficial", yet public versions of BLT. If people run into trouble with these versions, I'm encouraging them to contact me instead of George. Likewise, if someone wants to contribute patches, these should be made against the latest "unofficial" release and sent to me; I'll then try to incorporate them into my source tree and to release an updated version ASAP. -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
