286 B<gpgsigs> - annotate list of GnuPG keys with already done signatures
290 B<gpgsigs> [-r] [-f I<charset>] [-t I<charset>] I<keyid>I<[>B<,>I<keyidI<[>B<,>I<...>I<]>>I<]> F<keytxt> [F<outfile>]
294 B<gpgsigs> was written to assist the user in signing keys during a keysigning
295 party. It takes as input a file containing keys in C<gpg --list-keys> format
296 and prepends every line with a tag indicating if the user has already signed
297 that uid. When the file contains C<MD5 Checksum:> or C<SHA1 Checksum:> lines
298 and placeholders (C<__ __>), the checksum is inserted.
306 Call I<gpg --recv-keys> before creating the output.
310 Convert F<keytxt> from I<charset>. The default is ISO-8859-1.
314 Convert UIDs to I<charset>. The default is derived from LC_ALL, LC_CTYPE, and
315 LANG, and if all these are unset, the default is ISO-8859-1.
319 Use this keyid (8 or 16 byte) for annotation. Multiple keyids can be separated
324 Read input from F<keytxt>.
328 Write output to F<outfile>. Default is stdout.
334 The following key signing parties are using B<gpgsigs>:
336 http://www.palfrader.org/ksp-lt2k4.html
338 http://www.palfrader.org/ksp-lt2k5.html
342 B<GnuPG> is known to change its output format quite often. This version has
343 been tested with gpg 1.2.5 and gpg 1.4.1. YMMV.
