View source for LHA/LHarc self-extracting archive

== Identification ==
LHarc/LHA self-extracting archives contain a text message that will be printed when the files are extracted, which could be useful for format identification. Unfortunately, the message is not consistently located or formatted.

An example of such a message is "<code>LHarc's SFX 1.13S (c) Yoshi, 1989</code>". It contains a version number (which may only be approximate), and usually an "S" or "L" suffix indicating Small or Large model.

The following table summarizes most of the DOS formats.
