=head1 NAME

ctan-o-mat - Validate and upload a package for CTAN

=head1 SYNOPSIS

ctan-o-mat [options] [<package configuration>]

=head1 DESCRIPTION

This program can be used to automate the upload of a package to the
Comprehensive TeX Archive Network (https://www.ctan.org). The description
of the package is taken from a configuration file. Thus it can be updated
easily without the need to fill a Web form with the same old information
again and again.

The provided information is validated in any case. If the validation
succeeds and not only the validation is requested then the provided
archive file is placed in the incoming area of the CTAN for further
processing by the CTAN team.

In any case any finding during the validation is reported at the end
of the processing. Note that the validation is the default and a
official submission has to be requested by the an appropriate command
line option.

B<ctan-o-mat> requires an Internet connection to the CTAN server. Even the
validation retrieves the known attributes and the basic constraints
from the server.


=head1 CONFIGURATION

The default configuration is read from a file with the same name as
the current directory an the extension .pkg. This file name can be
overwritten on the command line.

The configuration depends on the features currently supported by the
CTAN server.
Since these features can change over time the configuration is not
hard-coded in B<ctan-o-mat>. You can request an empty template of the
configuration via the command line parameter C<--init>.


=head1 OPTIONS

=over 4

=item -h

=item --help

Print this short summary about the usage and exit the program.

=item -i

=item --init

Create an empty template for a configuration.

=item --list licenses

List the known licenses of CTAN to the standard output stream.
Each license is represented as one line. The line contains the fields
key, name, free indicator. Those fields are separated by tab characters.
Afterwards the program terminates without processing any further arguments.

=item --config <package configuration>

=item --pkg <package configuration>

=item --package <package configuration>

Set the package configuration file.

=item -s

=item --submit

Upload the submission, validate it and officially submit it to CTAN it the 
validation succeeds.

=item -v

=item --verbose

Print some more information during the processing (verbose mode).

=item --version

Print the version number of this program and exit.

=item --validate

=item -n

=item --noaction

Do not perform the final upload. The package is validated and the
resulting messages are printed. 

=item <package>

This parameter is the name of a package configuration
(see section CONFIGURATION) contained in a file.
If not set otherwise the package configuration defaults to the
name of the current directory with C<.pkg> appended.

=back


=head1 ENVIRONMENT

The following environment variables are recognized by B<ctan-o-mat>.

=over 4

=item CTAN_O_MAT_URL

The value is the URL prefix for the CTAN server to be contacted. The default
is C<https://ctan.org/submit>. The complete URL is constructed by appending
C<validate>, C<upload>, or C<fields> to use the respective CTAN REST API.

=back


=head1 CONNECTING VIA PROXIES

If you need to connect to the Internet via a proxy then this can be achieved
by setting some environment variables before running B<ctan-o-mat>.
To redirect the request via the proxy simply define an environment variable
C<http_proxy> to point to the proxy host -- including protocol and port as
required. Note that the name of the environment variable is supposed to be in
B<lower> case.

The program can not be used without a working connection to the
Internet.
