Need help to make the good choices :-)

See comments of Latouss in the duplicate issue #106.

Also, in installation script, it could be a good idea to allow user to copy bash_completion.sh into /etc/bash_completion.d/ folder (and not only ask him to add a line in its bashrc)
=> cp $(ROOT_DIR)/install/bash_completion.sh /etc/bash_completion.d/twgit
/!\ We need sudo to do this

bash_completion will be available for all users
AND
users who don't install twgit don't know there is a bash_completion file, so can't install it

In my mind the steps are :

• Store twgit into /usr/share (need sudo)
• Create folder /home/ltoussaint/.twgit : features_subject, log and error path will be stored in this folder
• Copy bash_completion.sh in /etc/bash_completion.d folder
• Copy bash_git.sh in /etc/profile.d ?
• Change autoupdate system : we can't update twgit without sudo
