Browse Source 
By setting the default value of PROG to the basname of whatever the
filename is, we allow bash_autocomplete to be copied into
/etc/bash_completion.d without modification.

#### To Distribute
Copy and modify `autocomplete/bash_autocomplete` to use your program name
rather than `$PROG` and have the user copy the file into
`/etc/bash_completion.d/` (or automatically install it there if you are
distributing a package). Alternatively you can just document that users should
source the generic `autocomplete/bash_autocomplete` with `$PROG` set to your
program name in their bash configuration.
Copy `autocomplete/bash_autocomplete` into `/etc/bash_completion.d/` and rename
it to the name of the program you wish to add autocomplete support for (or
automatically install it there if you are distributing a package). Don't forget
to source the file to make it active in the current shell.
```
sudo cp src/bash_autocomplete /etc/bash_completion.d/<myprogram>
source /etc/bash_completion.d/<myprogram>
```
Alternatively, you can just document that users should source the generic
`autocomplete/bash_autocomplete` in their bash configuration with `$PROG` set
to the name of their program (as above).
## Contribution Guidelines
Feel free to put up a pull request to fix a bug or maybe add a feature. I will give it a code review and make sure that it does not break backwards compatibility. If I or any other collaborators agree that it is in line with the vision of the project, we will work with you to get the code into a mergeable state and merge it into the master branch.
