=head1 NAME
dump-asy.pl - Render the layout tree using asymptote
=head1 SYNOPSIS
dump-asy.pl [workspace]
=head1 EXAMPLE
Render the entire tree, run:
./dump-asy.pl
Render the tree starting from the node with the specified name, run:
./dump-asy.pl 'name'
Render the entire tree, save in file 'file.eps' and show using gv, run:
./dump-asy.pl --save file.eps
=head1 OPTIONS

Enable or disable showing the result through gv. If disabled, an .eps file will
be saved in the current working directory. Enabled by default.
