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

409 B<gpgsigs> - annotate list of GnuPG keys with already done signatures
413 B<gpgsigs> [I<options>] I<keyid>I<[>B<,>I<keyidI<[>B<,>I<...>I<]>>I<]> F<keytxt> [F<outfile>]
417 B<gpgsigs> was written to assist the user in signing keys during a keysigning
418 party. It takes as input a file containing keys in C<gpg --list-keys> format
419 and prepends every line with a tag indicating if the user has already signed
420 that uid. When the file contains C<ALGO Checksum:> lines and placeholders
421 (C<__ __>), the checksum is inserted. ALGO can be set to the following algorithms:
422 MD5 SHA1 SHA256 or RIPEMD160.
430 Call I<gpg --recv-keys> before creating the output.
432 =item B<-f> I<charset>
434 Convert F<keytxt> from I<charset>. The default is ISO-8859-1.
436 =item B<-t> I<charset>
438 Convert UIDs to I<charset>. The default is derived from LC_ALL, LC_CTYPE, and
439 LANG, and if all these are unset, the default is ISO-8859-1.
443 Refresh the UID lists per key from gpg. Useful when UIDs were added or revoked
444 since the input text was generated.
448 Generate LaTeX output, including photo IDs. Implies B<--refresh>.
449 B<Note:> This writes eps files to the current directory.
453 Use this keyid (8 or 16 byte) for annotation. Multiple keyids can be separated
458 Read input from F<keytxt>.
462 Write output to F<outfile>. Default is stdout.
468 The following key signing parties are using B<gpgsigs>:
470 http://www.palfrader.org/ksp-lt2k4.html
472 http://www.palfrader.org/ksp-lt2k5.html
476 B<GnuPG> is known to change its output format quite often. This version has
477 been tested with gpg 1.2.5 and gpg 1.4.1. YMMV.
