[tor-commits] [torsocks/master] Add -u/-p/-d to torsocks script

[dgoulet@xxxxxxxxxxxxxx]

commit f0250901ac3ecef397bd86782ebbc3ced7f0d502
Author: David Goulet <dgoulet@xxxxxxxxx>
Date:   Mon Mar 3 15:04:43 2014 -0500

    Add -u/-p/-d to torsocks script
    
    The -u, --user and -p, --pass are for the SOCKS5 authentication where
    -d, --debug is to set torsocks in DEBUG mode.
    
    Improve the usage output and make sure torsocks on/off is being sourced
    else exit with error.
