| Source at commit 429 created 13 years 9 months ago. By meklort, Updated module system. Hooks can now be used within modules when cetaion functions are called in chameleon. Note that onle two hooks currently exist, more need to be added. I also updated the HelloWorld module to use a hook instead of print out right away. | |
