# Developer's NOTE: This script should be tested against a true /bin/sh, which
# has notable differences from bash. By design, this script does not try to do
# too much, so as to be as cross-platform as possible.

#     Revision 1.7  2006/10/14 14:12:22  fabiankeil
#     Print warnings if the user tries to run Privoxy as root
#     or if the script is run without root privileges;
#     only use "--user" if run with root privileges and
#     don't depend on $USER being set to root. Fixes BR 779781.
#
#     Apparently $USER isn't set on all systems,
#     but it also didn't work if the user only
#     increased her privileges with su or sudo,
#     but still had her real uid in $USER.

#     Thanks to Florian Effenberger for reporting.

#     Revision 1.6  2006/07/18 14:48:47  david__schmidt
#     Reorganizing the repository: swapping out what was HEAD (the old 3.1 branch)
#     with what was really the latest development (the v_3_0_branch branch)
#
#     Revision 1.5.2.1  2002/10/17 17:04:22  hal9
#     Add from main trunk. Will be needed for make install.
#
#     Revision 1.5  2002/10/17 17:01:29  hal9

#
#     Revision 1.4  2002/09/11 01:15:02  hal9
#     Fix typo in variable. Now tested on Solaris and Linux, with defaults.
#
#     Revision 1.3  2002/09/11 01:09:14  hal9
#     Better handling of pidfile, and process owner.

#     -Rewrote script config section.
#     -Added comments to script.
