# Less filter for viewing non text files.

# combined lessfile and lesspipe to avoid duplication of decode stage
# shell is sure icky. I'm real tempted to rewrite the whole thing in Perl
#
# Unfortunately, this means that I have filename dependencies sprinkled
# throughout the code. If you don't want lessfile to be called that,
# you'll need to change the LESSFILE envar below.
#
# Usage: eval `lessfile` or eval `lesspipe`
#
# less passes in:
# $1 filename to be viewed with less (used by LESSOPEN)
# and possibly (if used by lessfile)
# $2 filename that was created during LESSOPEN
