+ =head1 DESCRIPTION
+ The C<mkcommitfeed.pl> script provides a command-line interface to
+ update an Atom Feed that is intended for providing commit logs for a
+ software developmenet project.
+ The script, when invoked, adds an Atom Entry that describes a change
+ made to the project's repository.
+ =head1 STANDARD INPUT
+ A description for the change must be specified to the standard input.
+ It is used as the plain text content of the atom:content element of
+ the Entry for the change to add.
+ Non-ASCII characters are not supported in this version of this script.
+ Maybe a future version of this script would support UTF-8.
+ =head1 ARGUMENTS
+ There are command-line options for the script.  Some of them are
+ required, while the others are optional.  As a general rule, an option
+ whose name begins with C<--entry> specifies a property for the Entry
+ to add, while an option whose name begins with C<--feed> specifies a
+ property for the entire Feed.  Option values for Feed properties might
+ not be used when updating an existing Feed document.
+ =over 4
+ =item C<--entry-author-mail I<[email protected]>> (optional)
+ Specifies the mail address of the person who made a change.  It is
+ used as the content of the C<atom:email> element of the C<atom:author>
+ element of the Entry.
+ If this option is not specified, but the standard input includes a
+ ChangeLog entry in the standard GNU format, then the mail address is
+ taken from the ChangeLog entry.  Otherwise, C<atom:email> element is
+ not specified.
+ The option value must be an RFC 2822 C<addr-spec> that does not match
+ C<obs-addr-spec> (i.e. standard email address format).  Otherwise the
+ generated Feed would be non-conforming.
+ =item C<--entry-author-name I<author-name>> (conditionally required)
+ Specifies the human readable name of the person who made a change.  It
+ is used as the content of the C<atom:name> element of the
+ C<atom:author> element of the Entry.
+ If this option is not specified, but the standard input includes a
+ ChangeLog entry in the standard GNU format, then the name is taken
+ from the ChangeLog entry.  If the standard input does not include a
+ GNU format ChangeLog entry, then the C<--entry-author-name> option
+ must be specified.
+ Non-ASCII characters are not supported in this version of this script.
+ =item C<--entry-content I<description>> (optional)
+ Specifies the description of the change.  It is used as the content of
+ the C<atom:content> element of the Entry, with C<type=text>.
+ If this option is specified, its value is used as if it were from the
+ standard input and the actual standard input, if any, is ignored.  If
+ neither this option nor the standard input is specified, then the
+ description is assumed as the empty string.
+ Non-ASCII characters are not supported in this version of this script.
+ =item C<--entry-title I<title>> (optional)
+ Specifies the title of the change.  It is used as the content of the
+ C<atom:title> element of the Entry, with C<type=text>.
+ If this option is not specified, then the date of the change, as well
+ as the name of the author, is used as title.
+ Non-ASCII characters are not supported in this version of this script.
+ =item C<--feed-author-mail I<[email protected]>> (optional)
+ Specifies the mail address of the author of the Feed.  It is used as
+ the content of the C<atom:email> element of the C<atom:author> element
+ of the Feed.
+ This option is ignored if the C<--feed-author-name> option is not
+ specified.
+ If this option is not specified, C<atom:email> element is not
+ specified.
+ The option value must be an RFC 2822 C<addr-spec> that does not match
+ C<obs-addr-spec> (i.e. standard email address format).  Otherwise the
+ generated Feed would be non-conforming.
+ This option is ignored if the Feed already has an C<atom:author>
+ element.
+ =item C<--feed-author-name I<author-name>> (optional)
+ Specifies the human readable name of the author of the Feed.  It is
+ used as the content of the C<atom:name> element of the C<atom:author>
+ element of the Feed.
+ If this option is not specified, the C<atom:author> element is not
+ specified in the Feed.
+ Non-ASCII characters are not supported in this version of this script.
+ This option is ignored if the Feed already has an C<atom:author>
+ element.
+ =item C<--feed-author-url I<url>> (optional)
+ Specifies the URI for the author (e.g. URL of the Web page for the
+ author).  It is used as the content of the C<atom:uri> element of the
+ C<atom:author> element of the Feed.
+ If the C<--feed-author-name> option is not specified, this option is
+ ignored.
+ If this option is not specified, the C<atom:uri> element is not
+ specified.
+ The option value must be a URI reference conforming to RFC 3986.  It
+ should be an absolute reference unless you understand what is the base
+ URL that is used to resolve a relative reference.  Non-ASCII
+ characters (i.e. IRI references) are not supported in this version of
+ this script.
+ This option is ignored if the Feed already has an C<atom:author>
+ element.
+ =item C<--feed-lang I<langtag>> (optional)
+ Specifies the natural language used in textual parts of the Feed.  It
+ is used as the value of C<xml:lang> attribute of the root element of
+ the Feed.
+ If this option is not specified, the default value I<i-default> is used.
+ This option is ignored if the Feed already exists and has a
+ C<atom:link> element.
+ =item C<--feed-license-url I<url>> (optional)
+ Specifies the URL that describes the license of the Feed.  It is used
+ as the C<href> attribute value of an C<atom:link> element whose C<rel>

+ is C<license> is not specified.
+ The option value must be a URI reference conforming to RFC 3986.  It
+ should be an absolute reference unless you understand what is the base
+ URL that is used to resolve a relative reference.  Non-ASCII

+ element.
+ =item C<--feed-related-url I<url>> (optional)
+ Specifies a related URL for the Feed.  Usually the URL for the project
+ Web page should be specified.  It is used as the C<href> attribute
+ value of an C<atom:link> element whose C<rel> is C<related>.
+ If this option is not specified, the C<atom:link> element whose C<rel>
+ is C<related> is not specified.
+ The option value must be a URI reference conforming to RFC 3986.  It
+ should be an absolute reference unless you understand what is the base
+ URL that is used to resolve a relative reference.  Non-ASCII
+ characters (i.e. IRI references) are not supported in this version of
