-//
-// - Directories should be searched in the following order: ~/.q3a/baseq3,
-// install dir (/usr/local/games/quake3/baseq3) and cd_path (/mnt/cdrom/baseq3).
-//
-// - Pak files are searched first inside the directories.
-// - Case insensitive.
-// - Unix-style slashes (/) (windows is backwards .. everyone knows that)
