This package includes 3 files: 00README: You are reading it. tcl_linux.tar: The Tcl-Tk (8.0p2) kernel downloaded from http://www.scriptics.com and compiled on a PC running Linux/SuSe with gcc. The package was generated to find at run time all its shared libraries under /usr/local/lib. Un-taring this package will put all the file under: ./tcl/ To run it you can either create symbolics links under /usr/local/bin /usr/local/lib /usr/local/include /usr/local/man to ../tcl/ or to move all the files under /usr/local This package also includes under ./tcl/bin an application called tkcon. tkcon is a tcl/tk console thats works on all environment supporting TclTk. See http://www.cs.uoregon.edu/research/tcl/script/tkcon/ (I'm not sure that my package includes the latest version). Of course you do not need to install this package if you have already Tcl/Tk 8.0 running on your machine. In this case you may have (test it before) to create some links into /usr/local/bin (lib include) to run the next Taco dedicated package. tcl_esrf_linux.tar: This package includes: libtcltacoapi4.2.so which is the new Tcl-Taco interface. For people who have already used the pervious Tcl-Taco package the major difference is that the previous specific interpreters tcl_api and wish_api do not exist anymore. Now you have to use the native interpreters tclsh and wish and to dynamically load the tcl-Taco interface like this: #!/usr/local/bin/wish (or tclsh) package require tcltacoapi ;# load the package pkgIndex.tcl: This file is the "catalogue" from which the interpreter will be able to dynamically load the package when executing the above mentioned command.This file _MUST_ be into /usr/local/lib (at least as a link). When you un-tar it all files are put under: ./tcl/lib. As explained above you can crate links under /usr/local/lib or move these files under /usr/local/lib. rrap: is a library I have written to speed up the development phase of an application. I'm currently writing the documentation and you will be informed when this doc is ready.
