On the webpage you are seeing, under the "CLIC_#" package to download, you could see a few diminute files having names without extension and similar to the CLIC modules. For instance, "coo", or "tet", etc. (similar to the folders "COO", "TET", etc.). These files contain the main source code with some improvement, or with fixed bugs, since the last # CLIC version. It is recommended to download and use these new modules: their location on your computer is inside the homonym folder within the CLIC_# folder: for exemple, "tet" goes to "TET", "coo" to "COO", etc. Before to replace your current homonym files by these new ones (the date is indicated), please rename first the current files in your computer as, for instance, "coo_old" or "tet_old". ------------------------------------------ To decompress the CLIC_#_tar.gz ------------------------------------------ * Windows: - Some trial versions of commercial unzipping software are free, but free use has time limits. If you want a truly "free" software (http://www.fsf.org), you can use 7zip for instance (http://www.spiroo.be/7zip). * Linux: - Many possibilities, depending on your distribution; I guess that for all distributions, the following procedure is valid: - open a terminal, - and enter as a user ($) the following instruction: tar -zxvf CLIC_#.tar.gz * MacOS X Just double click on the corresponding icon ------------------------------------------ Starting the CLIC ------------------------------------------ LINUX, WINDOWS ------------------------------------------ - To open the CLIC, you must enter the CLIC folder and search for the files "clicwin" (or "clicwin64"), or "cliclin" (or "cliclin64") according to the system used (Windows or Linux, 32 or 64 bits machines). - Click on one of these files to boot CLIC. ------------------------------------------ MAC OS X ------------------------------------------ - To open the CLIC, you must enter the CLIC_# folder (inside the CLIC folder) and search for the file "maclic.tcl". It should be recognized by the TclTk included in the system, otherwise try to open it using "wish". To make everything run, please make "tclkitmac" executable (use the terminal, enter the folder and write "chmod +x tclkitmac". ------------------------------------------ First use of the CLIC (not for MacosX users) ------------------------------------------ - The first time you open CLIC, the program asks a weird question, kind of: "Where am I ?". A click on the button that asks the question, and you can navigate through your hard disk to the file "clic.tcl" (inside the CLIC folder). You select the file and "open" it. That's it. (If the folder CLIC stays at the same place, this question is not going to bother you anymore. Otherwise, you will have to follow the recommendation that will appear: to delete a given (hidden) file, and to open all over again.) Using CLIC (o. help) ------------------------------------------ Each module has its corresponding information on the website: http://www.mome-clic.com Good luck!
