Please note that modules are not supposed to contain any specific code for a
platform or a distribution, even if nothing block you doing so. It is highly
recommended to use configurations files to introduce any platform dependent
code. Additionally, it will be possible to create system dependent modules using
naming convention in the style module_name.debian.x86_64.sh (awaited for version

## 5. Contact and more information
### 5.1. New users
As this project is very new and as I have no idea of who will use it, if you do
so, I'll be very happy if you simply mail me to let me know, especially if you
don't plan to contribute.
### 5.1. How to contribute?
If you want to contribute, the best is to use git and push your changes in a
branch you made for that purpose. If you want to submit a patch, you can send it
by mail to the maintainor of init.sh.
### 5.2. How to contribute?
You are free to improve and contribute as you wish. If you have no idea what to
do or want some direction, you can check the [to do list](./doc/todo.md),
containing desired future improvements. Make sure you always have the latest
development version before starting your work.
It's heavily recommended to use git to obtain latest copy of init.sh tree. Make
sure your git is configured for contribution. Please contact me to obtain push
authorisations, or, if you want to submit a patch, you can send it by mail to
the maintainor of init.sh.
You can improve anything you want, but keep in mind init.sh have to stay small
and simple. If your idea cannot be written using Bash scripting, maybe that
means you're going to far in the improvement.
Code written in Python or Perl might be accepted as long as it's not mobilizing
a lot of dependencies (forget big framework). Core script will remain in Bash
whatever the evolutions of init.sh will be.

# This is init.sh to do list
There's no specific order in that list. All that is subject to appear in version
1.x.y of ```init.sh```.
* Better error management system
* Fix ```--keep-going``` option not properlly working
* Add a function for booleans to accept true, yes and 1, and false, no and 0 answers
* Add network configuration module
* More modules
* Add support for CentOS
* Add support for Slackware
* Add support for more distros including BSDs
* Improve output
* Add ```--quiet``` option to hide run commands output
Here is ideas for version 2 of ```init.sh```:
* Support for system dependant modules
* Better configuration file design with a proper parser (ini style maybe)
* Configuration designer (CCmake style maybe), can't be done in Bash
