FSOVL-HANDLER
This is a filesystem overlay handler that provides automatic compression
and decompression of files. Openning a file automatically decompresses
it. Writing to a file automatically compresses it. Files openned for
read are blocked into memory in 4K segments while files openned for
write are brought entirely into memory and then compressed on close.
Seek operations are fast but an actual Read() after a seek may be slow.
Files with extensions of .Z .LHA .LZH .ZOO .ZIP are not compressed.
The first 8 bytes of the comment field of a file is reserved to store
its actual length. This is transparent for operations done through the
FSOVL-HANDLER.
