Hello All, I am planning to write a elisp script (something similar to gdb mode in emacs). The script needs to use emacs gui for highlighting and moving around some custom log files. Do I need to make source code of the script and related backend scripts/programs (used for log file parsing, etc. ) because of the GNU public license? Sorry for asking such a stupid question. I tried to look for the answer but could not. -- With warm regards, Vivek. J. Joshi.
