SCOLASYNC(1)						       scolasync User Manual						      SCOLASYNC(1)

NAME

       scolasync - a file manager dedicated to dealing with a collection of removable media, like music mobile players. It makes easier to copy
       files to a set of removable media, and to copy files from them.

SYNOPSIS

       scolasync [{-c | --check}]

DESCRIPTION

       scolasync allows you to send a series of files towards a set of removable media. Every individual removable storage device is identified,
       for example to its owner. Then, later, you can retreive modified files from the same collection of removable media and track the
       modifications attributable to each owner.

       A possible usage is with students learning a foreign language: they are given homework on their USB sticks, and they bring them back with
       modified contents to get scores.

OPTIONS

       -c , --check
	   Enables checkboxes to select a subset of the usb storage media currently plugged to your computer, even if the checkboxes are not
	   wanted in the preferences of the application.

FILES

       ${HOME}/.scolasync/db
	   A database containing the preferences of the application, and the mapping between owners and USB storage media.

       /usr/share/scolasync/marques.py
	   A dictionary of pecularities which come with some brands of USB storage media.

       ${HOME}/.scolasync/marques.py
	   This dictionary overrides the settings in the system-wide configuration.

       ${HOME}/.scolasync/scolasync.log
	   A log file for the application.
