\fBefsextract\fR [\fI-h\fR|\fI-V\fR]
.SH DESCRIPTION
.I efsextract
extracts files from an SGI CD image, or an EFS file system.
.P
Silicon Graphics (SGI) was a computer company that existed from 1981 to
2009. During this period, they shipped software for their computers,
sometimes on CD, and often not using the standard ISO9660 file system.
These discs are instead simply hard disc images pressed to CD. Thus,
they have an SGI disk label and an EFS partition.
.P
Most systems cannot understand this sort of disc format. This tool was
developed to allow non-SGI systems to at least be able to extract files
from such discs.
