bash completion for chicken tools

The Debian bash package features support for command line completion through the file /etc/bash_completion. This page of the chicken wiki provides a file to add completion for the chicken tools in bash.

Currently, only chicken-setup is supported. Hopefully csi and csc will follow.

Chicken 4 is currently not supported.

Use

Copy the following code in a file named chicken in /etc/bash_completion.d. Alternatively, source it after /etc/bash_completion (which is sourced from ~/.bashrc or elsewhere).

# chicken-setup command line completion for bash.
#
# version 0.2 -- 2007.01.13 -- vo minh thu
#  - chicken-setup <tab> completes for *.egg files.
# version 0.1 -- 2007.01.13 -- vo minh thu
