>#!/bin/sh
>#
># To use this filter with less, define LESSOPEN:
># export LESSOPEN="|/usr/bin/lesspipe.sh %s"
>#
># The script should return zero if the output was valid and non-zero
># otherwise, so less could detect even a valid empty output
># (for example while uncompressing gzipped empty file).
># For backward-compatibility, this is not required by default. To turn
># this functionality there should be another vertical bar (|) straight
># after the first one in the LESSOPEN environment variable:
># export LESSOPEN="||/usr/bin/lesspipe.sh %s"
