Format details
New SWG format is based on generalized LHA format. It is approximately parsable as LHA, but the fields starting with the filename field seem to be repurposed, and it has a custom "compression scheme".
Identification
New format files have ASCII "-sw1-" at offset 2.
At least some old format files start with "SWAGOLX.EXE".
