=head1 NAME
dh_phpcomposer - calculates PHP Composer substvars
=head1 SYNOPSIS
B<dh_phpcomposer> [S<I<debhelper options>>] [S<I<options>>]
=head1 DESCRIPTION
B<dh_phpcomposer> is a debhelper program that is responsible for generating
the B<${phpcomposer:*}> substitutions and adding them to substvars files.
The program will look for F<composer.json> file in the package root,
and will use this information to generate:
=over 2
=item *
B<${phpcomposer:name}> and B<${phpcomposer:description}>
=item *
B<${phpcomposer:Debian-require}>, B<${phpcomposer:Debian-require-dev}>,
B<${phpcomposer:Debian-conflict}>, B<${phpcomposer:Debian-replace}>,
B<${phpcomposer:Debian-provide}>, B<${phpcomposer:Debian-suggest}> and
B<${phpcomposer:Debian-recommend}>
=back
Those variables will be substituted into the package's F<control>
file wherever the token B<${phpcomposer:*}> are placed.
This feature requires pkg-php-tools (>= 1.7~).
=head1 OPTIONS
=over 4
=item B<--sourcedirectory=>I<directory>
Assume that the original package source tree is at the specified directory
rather than the top level directory of the Debian source package tree.
This feature requires pkg-php-tools (>= 1.14~).
