# Program to generate fish completion function for wajig.
|
|
# It runs 'wajig command' and analyzes the output to build a
|
|
# completion file which it writes to stdout.
|
|
# To use the result, direct stdout to
|
|
# ~/.fish.d/completions/wajig.fish.

# Author Reuben Thomas, from Don Rozenberg's bash_completion.py and
|
|
# fish's apt-get.fish.
