Patch anatomy

Patch consists of patch file (with extension LFC) and small patch description file (with extension LFI).

Patch file contains informations needed to apply the patch (all files to Add, information about files to Delete and differential information about files to Modify).

Patch description file contains information about default application path and main module file name (see Using LFPATCH.EXE). Default name for patch description file is LFPATCH.LFI. When this file is located in the patching program (LFPATCH) directory, it will be used automatically. Otherwise, the patch description file name has to be given as command line parameter (e.g. LFPATCH MYPATCH.LFI).
