53 keyid is a long or short keyid (e.g. DE7AAF6E94C09C7F or 94C09C7F)
54 separate multiple keyids with ','
55 -r call gpg --recv-keys before proceeding
56 -f <charset> convert <keytxt> from charset
57 -t <charset> convert UIDs to charset in output
58 --refresh regenerate UID lists on keys
59 --latex generate LaTeX output including photo IDs

396 B<gpgsigs> - annotate list of GnuPG keys with already done signatures
400 B<gpgsigs> [I<options>] I<keyid>I<[>B<,>I<keyidI<[>B<,>I<...>I<]>>I<]> F<keytxt> [F<outfile>]
404 B<gpgsigs> was written to assist the user in signing keys during a keysigning
405 party. It takes as input a file containing keys in C<gpg --list-keys> format
406 and prepends every line with a tag indicating if the user has already signed
407 that uid. When the file contains C<MD5 Checksum:> or C<SHA1 Checksum:> lines
408 and placeholders (C<__ __>), the checksum is inserted.
416 Call I<gpg --recv-keys> before creating the output.
418 =item B<-f> I<charset>
420 Convert F<keytxt> from I<charset>. The default is ISO-8859-1.
422 =item B<-t> I<charset>
424 Convert UIDs to I<charset>. The default is derived from LC_ALL, LC_CTYPE, and
425 LANG, and if all these are unset, the default is ISO-8859-1.
429 Refresh the UID lists per key from gpg. Useful when UIDs were added or revoked
430 since the input text was generated.
434 Generate LaTeX output, including photo IDs. Implies B<--refresh>.
435 B<Note:> This writes eps files to the current directory.
439 Use this keyid (8 or 16 byte) for annotation. Multiple keyids can be separated
444 Read input from F<keytxt>.
448 Write output to F<outfile>. Default is stdout.
454 The following key signing parties are using B<gpgsigs>:
456 http://www.palfrader.org/ksp-lt2k4.html
458 http://www.palfrader.org/ksp-lt2k5.html
462 B<GnuPG> is known to change its output format quite often. This version has
463 been tested with gpg 1.2.5 and gpg 1.4.1. YMMV.
