%description
less is a text file browser and pager similar to more. It allows
backward as well as forward movement within a file. Also, less does not
have to read the entire input file before starting. It is possible to
start an editor at any time from within less.

Dear user,
the 'less' application, thanks to its preprocessor, is able to show even binary
formats using calls to external commands. Since not every user finds this
feature plausible, you have the opportunity to customize behavior of 'less'
using the environment variable LESS_ADVANCED_PREPROCESSOR. By default, it's set
to "no" in /etc/profile -- thus if you require less to handle binary formats,
set this in your startup scripts:
export LESS_ADVANCED_PREPROCESSOR="yes"
Remark for experienced users:
If you had already set this switch and want to temporarily override it, you can
force 'less' to read a file from its standard input instead, e.g.:
less < dumb.ps
will show the source PostScript, and not the "rendered" result.
