lesspipe.sh is an input filter for the pager less. It is able to process a wide
variety of file formats. It enables users to deeply inspect archives and to
display the contents of files in archives without having to unpack them before.
That means file contents can be properly interpreted even if the files are
compressed and contained in a hierarchy of archives (often found in RPM or DEB
archives containing source tarballs). The filter is easily extensible for new
formats. The input filter is a bash script, but works as well as a zsh script.
For zsh and bash tab completion mechanisms for archive contents are provided.
