43 =item B<caff> [-eEmMRS] [-u I<yourkeyid>] I<keyid> [I<keyid> ..]
49 CA Fire and Forget is a script that helps you in keysigning. It takes a list
50 of keyids on the command line, fetches them from a keyserver and calls GnuPG so
51 that you can sign it. It then mails each key to all its email addresses - only
52 including the one UID that we send to in each mail, pruned from all but self
53 sigs and sigs done by you.
59 =item B<-e>, B<--export-old>
61 Export old signatures. Default is to ask the user for each old signature.
63 =item B<-E>, B<--no-export-old>
65 Do not export old signatures. Default is to ask the user for each old
68 =item B<-m>, B<--mail>
70 Send mail after signing. Default is to ask the user for each uid.
72 =item B<-M>, B<--no-mail>
74 Do not send mail after signing. Default is to ask the user for each uid.
76 =item B<-R>, B<--no-download>
78 Do not retrieve the key to be signed from a keyserver.
80 =item B<-S>, B<--no-sign>
84 =item B<-u> I<yourkeyid>, B<--local-user> I<yourkeyid>
86 Select the key that is used for signing, in case you have more than one key.
94 =item $HOME/.caffrc - configuration file
98 =head1 CONFIGURATION FILE OPTIONS
100 The configuration file is a perl script that sets values in the hash B<%CONFIG>.

118 Your email address, used in From: lines. B<REQUIRED>.
120 =item B<keyid> [list of keyids]
122 A list of your keys. This is used to determine which signatures to keep
123 in the pruning step. If you select a key using B<-u> it has to be in
124 this list. B<REQUIRED>.
126 =head2 General settings
128 =item B<caffhome> [string]

140 Path to the GnuPG binary which is used to sign keys. Default: what
143 =item B<gpg-delsig> [string]
145 Path to the GnuPG binary which is used to split off signatures. This was
146 needed while the upstream GnuPG was not fixed. Default: what B<gpg>
149 =item B<secret-keyring> [string]
151 Path to your secret keyring. Default: B<$HOME/.gnupg/secring.gpg>.
153 =item B<also-encrypt-to> [keyid]
155 An additional keyid to encrypt messages to. Default: none.
157 =item B<gpg-sign-args> [string]
159 Additional arguments to pass to gpg. Default: none.
161 =head2 Keyserver settings
163 =item B<keyserver> [string]
165 Keyserver to download keys from. Default: B<subkeys.pgp.net>.
167 =item B<no-download> [boolean]

176 If true, then skip the signing step. Default: B<0>.
178 =item B<ask-sign> [boolean]

181 This is useful for offline signing. Default: B<0>.
183 =item B<export-sig-age> [seconds]
185 Don't export UIDs by default, on which your latest signature is older
186 than this age. Default: B<24*60*60> (i.e. one day).

192 Do not prompt for sending mail, just do it. Default: B<0>.

196 Do not prompt for sending mail. The messages are still written to
197 $CONFIG{caffhome}/keys/. Default: B<0>.
199 =item B<mail-template> [string]
201 Email template which is used as the body text for the email sent out
202 instead of the default text if specified. The following perl variables
203 can be used in the template:
207 =item B<{owner}> [string]
209 Your name as specified in the L<B<owner>|/item_owner__5bstring_5d> setting.
211 =item B<{key}> [string]
213 The keyid of the key you signed.
215 =item B<{@uids}> [array]
217 The UIDs for which signatures are included in the mail.
221 =item B<bcc> [string]
223 Address to send blind carbon copies to when sending mail.
