To use this Adobe Photoshop extension, set environment variable
PHOTOSHOP_OPT_EXT to include the name of this extension. For
example, if this is the only optional extension you wish to use:

C-shell:
	setenv PHOTOSHOP_OPT_EXT 'DisableScratchPageCompression'

Bourne or Korn Shell:
	PHOTOSHOP_OPT_EXT='DisableScratchPageCompression'
	export PHOTOSHOP_OPT_EXT

If you want to use multiple optional extensions, separate the names with colons.

See the Adobe Photoshop Getting Started guide for more information.

By default, this version of Adobe Photoshop compresses pages before writing them
to the scratch file.  This does not result in a smaller scratch file since
Photoshop must still reserve space for the uncompressed pages.  For slow
disk drives or SCSI implementations, however, the reduction in the data to
be transferred to or from disk more than compensates for the time needed to
compress or decompress the data.  For fast disk drives and SCSI
implementations, this is not the case.

Installing "Disable Scratch Compression" disables scratch page compression 
and should provide a slight performance improvement on machines with 
fast disk drives and SCSI implementations.
