It could be platform-specific, and on non-win32 it just says to go to the website, perhaps?
I think that's a bad idea. Obviously it has to be platform specific, but I don't see why it can't detect the platform and do the platform specific code for that one platform. For example:
-Detect system
-If linux, execute linux command for opening the page in a web browser/default web browser/firefox/whatever linux does
-If windows, execute windows command for opening page in the default web browser.
-Other OS's are a minority. If possible, try and implement such features. If not, show a generic message box with a link to the online version
Also, please distribute the files
with MG. Don't just open the web browser to the MegaGlest site's page... It is incredibly annoying and not the least bit helpful for those of us who play offline/away/while traveling/etc. It requires no extra work, and web pages are very small filesize compared to the rest of MG. Besides, we can handle the different file path types with this method anyway, since we are detecting the OS.
