Release 1

How to install:

in your Portal 2/bin/ folder (not the one containing client.dll and server.dll) rename filesystem_stdio.dll to filesystem_stdio_og.dll
then move the attached filesystem_stdio.dll into the bin folder.

Adding assets/files to the default custom search path:

For regular Portal 2:
by default the patch looks for files in a folder named "custom" in the same directory as the game .exe, make sure to create this folder. once its made you can use it like normal.

For Portal 2 sourcemods:
it will look for the custom folder in your sourcemod's root folder, so the same folder as the one with the "gameinfo.txt".
