I have to admit that I didn't consider that there could already be a TCL
unit available. Therefore I did a full header translation for TCL 8.4 (which
was the current version at that time). Additionally I added an object
oriented wrapper to ease the programming.

Please see at https://github.com/hansiglaser/pas-tcl for the sources.

I use this library (together with pas-readline) in several projects (e.g.
"eztool" on Github), some of which are actively in development but not yet
published. It currently works perfectly with TCL 8.5, but I didn't (yet)
update the header translations.

I'd be happy for any help improving the library or even inclusion in FPC!

Bye

PS: I've mentioned the TCL library in the fpc-pascal list some time ago:
