/* Source control utility. Backup/Restore files. Run actions on any change in a directory.
 * Create hard copies and display file diffs.
 * Verify content, ownserships and rights.
 * Can execute one -or more- commands, or reload a browser tab, at a file change.
 * Restore file on demand.
 * Automatize dev flow. Example, run a test script, or compile at a file change.
 * Recursive to the whole directory tree.
 * Backup all files versions, keeping the flow by timestamp.
 * Does not alter the dev target working dir.
 * Exclude git hidden files. Exclude vim and nano .swp files.
 * 
 * PARAMS:
 * -e  --exec      <command>    Execute command (Use quotes if necessary)
 * -r  --reload    <program>    Reload target program (F5)
 * -x  --inject    <js file>    javascript injection in browser console
 *     --purge     Delete cache
 * 
 * Browse DIR historic and restore files
 * Those are all changes made in the current DIR, by date, while the current program was running
 * -b --browse
 *
 * Examples:
 * # Reload focused tabs of many browsers
 * -r firefox -r chromium
 * # Run commands
 * ./scs -r firefox -e "ls -ltrapR"
 * # Inject alert("xss") in the currently focused Firefox tab
 *  -x script.js
