cave.idc

	// cave.idc : An IDA IDC script to find alignment blocks
	// (also called 'code cave') in an IDA database.
	// Useful when you need to add code to a binary file
	// Say for example you found an exploitable bug in a program
	// and you don't want to wait for the developer to provide a bugfix,
	// you can add your own code to the alignment block in order to manually
	// fix the bug.

	// Code by trapflag
	// bugfixed by death
