| 176 |
=head1 DESCRIPTION |
| 177 |
|
| 178 |
The C<mkcommitfeed.pl> script provides a command-line interface to |
| 179 |
update an Atom Feed that is intended for providing commit logs for a |
| 180 |
software developmenet project. |
| 181 |
|
| 182 |
The script, when invoked, adds an Atom Entry that describes a change |
| 183 |
made to the project's repository. |
| 184 |
|
| 185 |
=head1 STANDARD INPUT |
| 186 |
|
| 187 |
A description for the change must be specified to the standard input. |
| 188 |
It is used as the plain text content of the atom:content element of |
| 189 |
the Entry for the change to add. |
| 190 |
|
| 191 |
Non-ASCII characters are not supported in this version of this script. |
| 192 |
Maybe a future version of this script would support UTF-8. |
| 193 |
|
| 194 |
=head1 ARGUMENTS |
| 195 |
|
| 196 |
There are command-line options for the script. Some of them are |
| 197 |
required, while the others are optional. As a general rule, an option |
| 198 |
whose name begins with C<--entry> specifies a property for the Entry |
| 199 |
to add, while an option whose name begins with C<--feed> specifies a |
| 200 |
property for the entire Feed. Option values for Feed properties might |
| 201 |
not be used when updating an existing Feed document. |
| 202 |
|
| 203 |
=over 4 |
| 204 |
|
| 205 |
=item C<--entry-author-mail I<[email protected]>> (optional) |
| 206 |
|
| 207 |
Specifies the mail address of the person who made a change. It is |
| 208 |
used as the content of the C<atom:email> element of the C<atom:author> |
| 209 |
element of the Entry. |
| 210 |
|
| 211 |
If this option is not specified, but the standard input includes a |
| 212 |
ChangeLog entry in the standard GNU format, then the mail address is |
| 213 |
taken from the ChangeLog entry. Otherwise, C<atom:email> element is |
| 214 |
not specified. |
| 215 |
|
| 216 |
The option value must be an RFC 2822 C<addr-spec> that does not match |
| 217 |
C<obs-addr-spec> (i.e. standard email address format). Otherwise the |
| 218 |
generated Feed would be non-conforming. |
| 219 |
|
| 220 |
=item C<--entry-author-name I<author-name>> (conditionally required) |
| 221 |
|
| 222 |
Specifies the human readable name of the person who made a change. It |
| 223 |
is used as the content of the C<atom:name> element of the |
| 224 |
C<atom:author> element of the Entry. |
| 225 |
|
| 226 |
If this option is not specified, but the standard input includes a |
| 227 |
ChangeLog entry in the standard GNU format, then the name is taken |
| 228 |
from the ChangeLog entry. If the standard input does not include a |
| 229 |
GNU format ChangeLog entry, then the C<--entry-author-name> option |
| 230 |
must be specified. |
| 231 |
|
| 232 |
Non-ASCII characters are not supported in this version of this script. |
| 233 |
|
| 234 |
=item C<--entry-content I<description>> (optional) |
| 235 |
|
| 236 |
Specifies the description of the change. It is used as the content of |
| 237 |
the C<atom:content> element of the Entry, with C<type=text>. |
| 238 |
|
| 239 |
If this option is specified, its value is used as if it were from the |
| 240 |
standard input and the actual standard input, if any, is ignored. If |
| 241 |
neither this option nor the standard input is specified, then the |
| 242 |
description is assumed as the empty string. |
| 243 |
|
| 244 |
Non-ASCII characters are not supported in this version of this script. |
| 245 |
|
| 246 |
=item C<--entry-title I<title>> (optional) |
| 247 |
|
| 248 |

| 249 |
C<atom:title> element of the Entry, with C<type=text>. |
| 250 |
|
| 251 |
If this option is not specified, then the date of the change, as well |
| 252 |
as the name of the author, is used as title. |
| 253 |
|
| 254 |
Non-ASCII characters are not supported in this version of this script. |

|
| 256 |

| 258 |
Specifies the mail address of the author of the Feed. It is used as |
| 259 |
the content of the C<atom:email> element of the C<atom:author> element |
| 260 |

| 263 |
specified. |

| 268 |
The option value must be an RFC 2822 C<addr-spec> that does not match |
| 269 |
C<obs-addr-spec> (i.e. standard email address format). Otherwise the |
| 270 |
generated Feed would be non-conforming. |
| 271 |
|
