Bash completion
===============

Environment variables
---------------------

*COMP_CONFIGURE_HINTS*::
    If set and not null, `configure` completion will return the entire option
    string (e.g.  `--this-option=DESCRIPTION`) so one can see what kind of data
    is required and then simply delete the descriptive text and add one's own
    data.  If unset or null (default), `configure` completion will strip
    everything after the '=' when returning completions.


*COMP_CVS_REMOTE*::
    If set and not null, `cvs commit` completion will try to complete on
    remotely checked-out files.  This requires passwordless access to the
    remote repository.  Default is unset.


*COMP_KNOWN_HOSTS_WITH_HOSTFILE*::
    If set and not null (default), known_hosts completion will complement
    hostnames from ssh's known_hosts_files with hostnames taken from the file
    specified by the HOSTFILE shell variable (compgen -A hostname). If null,
    known_hosts completion will omit hostnames from HOSTFILE.  Omitting
    hostnames from HOSTFILE is useful if HOSTFILE contains many entries for
    local web development or ad-blocking.


*COMP_TAR_INTERNAL_PATHS*::
    If set and not null *before* sourcing bash_completion, `tar` completion
    will do correct path completion for tar file contents.  If unset or null,
    `tar' completion will do correct completion for paths to tar files.  See
    also README.
