# add-tor - Add a tor fingerprint line to the approved-routers file
|
|
#
|
|
# Tor's approved-routers file is expected to be versioned using RCS.
|
|
# This script checks for uncommitted changes, does a checkout of the
|
|
# file, adds the new fingerprint with a comment stating the server's
|
|
# operator, and commits the file to RCS again (using -u so that the
|
|
# working copy is not removed.
|
|
#
|
|
# Operator and fingerprint line are read from stdin.
|
|
#
|
|
# Before adding a fingerprint line, approved-routers is checked for
|
|
# rough syntactical correctness. This script also checks that the
|
|
# nickname and fingerprint to be added do not already exist in the
|
|
# binding list.
