5 # sig2dot v0.35 (c) 2005 Christoph Berg <cb@df7cb.de>
6 # Download from: http://ftp.debian.org/debian/pool/main/s/sig2dot/
8 # Parses output of "gpg --list-sigs" into a format
9 # suitable for rendering into a graph by graphviz
10 # (http://www.research.att.com/sw/tools/graphviz/) like so:
12 # $ gpg --list-sigs --keyring ./phillylinux.gpg | ./sig2dot.pl > phillylinux.dot
13 # $ neato -Tps phillylinux.dot > phillylinux.ps
14 # $ convert phillylinux.ps phillylinux.jpg
16 # Commandline options:
19 # Black and white / do not colorize.
22 # Render graph as it appeared on <date> (ignores more recent
23 # signatures). Date must be in the format "YYYY-MM-DD".
24 # Will also ignore keys that have since been revoked.
27 # Render all keys, even if they're not signed by any other key.
30 # Support localized output of GnuPG for unknown user IDs. For
31 # example, German users have to write (with sh quotation marks!)
32 # "[User-ID nicht gefunden]" if they use GnuPG with German
33 # messages. Default is "[User id not found]".
36 # Support localized output of GnuPG for revoked keys. For
37 # example, French users have to write "révoqué" if they use
38 # GnuPG with French messages. Default is "[revoked".
41 # Produces statistics file with number of signatures per node
49 # v0.9 2000-09-14 19:20 strip trailing whitespace from $id more cleanly
50 # v0.10 2000-09-14 19:33 skip revoked keys at the request of Peter Palfrader <ppalfrad@cosy.sbg.ac.at>
51 # v0.11 Nov 22 21:38 use ID for node name instead of username for uniqueness
52 # v0.12 Dec 15 16:20 use names instead of IDs again in stats.html
53 # v0.13 Jun 19 03:15 red is proportional to signatures
54 # v0.14 Jun 19 03:25 blue is proportional to other keys signed
55 # v0.15 Jun 20 17:16 fixed blue, green is proportional to ratio
56 # v0.16 Jun 20 18:55 uniqed %signedby
57 # v0.17 Jan 10 19:10 Use overlap=scale instead of fixed edge lengths. Requires new version of graphviz.
58 # v0.18 Jan 23 11:53 stats.html is now valid html (v.01 transitional)
59 # v0.23 May 3 18:52 bunch of new stuff, including -b flag (black & white), and fixes devision by zero error
60 # v0.24 May 3 18:59 add black outline to nodes, prettier (changed node attribute "color" to "fillcolor")
61 # v0.25 May 3 19:06 cleaned up anti- devision by zero code a little
62 # v0.26 May 4 00:08 strip all non-digit characters from $renderdate
63 # v0.27 May 10 00:23:49 2002 use {}'s to write 1 line per public key instead of one line per signature (much shorter)
64 # v0.28 Feb 13 2003 Change regex to handle option trust digit
65 # <kevin@rosenberg.net>
66 # v0.29 Feb 18 2003 Add -s option to optionally produce statistics file
67 # <kevin@rosenberg.net>
68 # v0.30 Feb 18 2003 Make --list-sigs regex more robust
69 # Marco Bodrato <bodrato@gulp.linux.it>
70 # v0.31 Jul 28 2003 Add -u option for localized output of GnuPG
71 # Marcus Frings <protagonist@gmx.net>
72 # further changes are documented in debian/changelog
