Many files on UNIX systems have one or more extensions specifying
their types. For example, a file that ends in `.c' is a file
containing a C program, while a file ending in `.tar.gz' is
a tar archive compressed with the gzip utility. Having a
default action for each file type, binded on the same key, seems to be a
good idea because you can use that key to obtain type specific
information about a file or to process it in some type specific way much
easier. The GIT package contains a script called
gitaction that is used to detect the current file type and
perform a type specific action. See section The GIT per file type action script, for more information.
