=head1 NAME
tlpsizes - list sizes of TeX Live schemes, collections, or packages
=head1 SYNOPSIS
tlpsizes [I<option>]... [I<tlpkg>]...
=head1 OPTIONS
=over 4
=item B<-schemes>
Report on all schemes if no I<tlpkg> is given.
=item B<-help>
Print this documentation and exit.
=back
The standard options B<-q>, B<-v>, and B<-logfile>=I<file> are also
accepted; see the C<process_logging_options> function in
L<TeXLive::TLUtils> for details.
=head1 DESCRIPTION
Print the size of each I<tlpkg>, in megabytes, largest first. If no
names are specified on the command line, list sizes of either all
collections, or, if C<-schemes> is specified, all schemes.
For collections and schemes, also output (on the same line) the
constituent packages and their sizes (also largest first), in kilobytes
this time.
