argument C<root> is given it will be initialized from the respective

file on the filesystem in the usual way.

These functions return a reference to a hash with package names as keys
and the sizes in bytes as values. The sizes are computed for the list of
package names given as the fourth argument, or all packages if not
specified. The difference between the two functions is that the C<_with_deps>
gives the size of packages including the size of all depending sizes.
If anything has been computed one additional key is synthesized,
C<__TOTAL__>, which contains the total size of all packages under
consideration. In the case of C<_with_deps> this total computation
does B<not> count packages multiple times, even if they appear
multiple times as dependencies.
If the third argument is a reference to a list of architectures, then
only the sizes for the binary packages for these architectures are used,
otherwise all sizes for all architectures are summed.

Returns the list of candidates for the given package in the
format
tag/revision
If the returned list is empty, then the database was not virtual and
no install candidate was found.
If the returned list contains undef as first element, the database
is virtual, and no install candidate was found.
The remaining elements in the list are all repositories that provide
that package.
Note that there might not be an install candidate, but still the
package is provided by a sub-repository. This can happen if a package
is present only in the sub-repository and there is no explicit pin
for that package in the pinning file.

=head1 OPTIONS
Options regarding the full TeX Live installation to be described are saved
in a package C<00texlive.config> as values of C<depend> lines. This special
package C<00texlive.config> does not contain any files, only depend lines
which set one or more of the following options:
=over 4
=item C<container_split_src_files/[01]>
=item C<container_split_doc_files/[01]>
These options specify that at container generation time the source and
documentation files for a package have been put into a separate container
named C<package.source.extension> and C<package.doc.extension>.
=item C<container_format/I<format>>
This option specifies a format for containers. The currently supported
formats are C<xz> and C<zip>. But note that C<zip> is untested.
=item C<release/I<relspec>>
This option specifies the current release. The first four characters must
be a year.
=item C<minrelease/I<relspec>>
This option specifies the minimum release for which this repository is
valid.
=back
To set these options the respective lines should be added to
C<00texlive.config.tlpsrc>.
