@@ -51,15 +51,6 @@ command line to allow code debugging in a different directory.  Basepath cannot
 be modified at all after startup.  Any files that are created (demos, screenshots,
 etc) will be created reletive to the base path, so base path should usually be writable.
 
-The "cd path" is the path to an alternate hierarchy that will be searched if a file
-is not located in the base path.  A user can do a partial install that copies some
-data to a base path created on their hard drive and leave the rest on the cd.  Files
-are never writen to the cd path.  It defaults to a value set by the installer, like
-"e:\quake3", but it can be overridden with "+set fs_cdpath g:\quake3".
-
-If a user runs the game directly from a CD, the base path would be on the CD.  This
-should still function correctly, but all file writes will fail (harmlessly).
-
 The "home path" is the path used for all write access. On win32 systems we have "base path"
 == "home path", but on *nix systems the base installation is usually readonly, and
 "home path" points to ~/.q3a or similar
@@ -93,21 +84,6 @@ trying to restrict demo / oem versions of the game with code changes.  Demo / oe
 should be exactly the same executables as release versions, but with different data that
 automatically restricts where game media can come from to prevent add-ons from working.
 
-After the paths are initialized, quake will look for the product.txt file.  If not
-found and verified, the game will run in restricted mode.  In restricted mode, only 
-files contained in demoq3/pak0.pk3 will be available for loading, and only if the zip header is
-verified to not have been modified.  A single exception is made for q3config.cfg.  Files
-can still be written out in restricted mode, so screenshots and demos are allowed.
-Restricted mode can be tested by setting "+set fs_restrict 1" on the command line, even
-if there is a valid product.txt under the basepath or cdpath.
-
-If not running in restricted mode, and a file is not found in any local filesystem,
-an attempt will be made to download it and save it under the base path.
-
-If the "fs_copyfiles" cvar is set to 1, then every time a file is sourced from the cd
-path, it will be copied over to the base path.  This is a development aid to help build
-test releases and to copy working sets over slow network links.

 File search order: when FS_FOpenFileRead gets called it will go through the fs_searchpaths
 structure and stop on the first successful hit. fs_searchpaths is built with successive
