LIB_format

LIB is the Game Maker
Library format introduced in GM 5.0.
LateralGM supports it, as well as a greatly
compressed alternative, LGL format.

LIBs can be edited with a Library Maker,
provided that the Lib ID is 1000 or greater (this is to prevent the user
from editing the official libs. If you still desire to view/edit the
official libs, simply alter it with a hex editor to make the Lib ID to
some number >= 1000). Interestingly, official libs all use the value
1 for Lib ID.

For notes on how to read this format, and other information, please see
Format info.
