=head1 NAME

ptomerge - merges pto projects

=head1 Synopsis

  ptomerge infile1.pto infile2.pto infile3.pto [...] outfile.pto

=head1 DESCRIPTION

Takes a list of .pto projects and joins them together into a single .pto
project.  Projects at the begining of the list get priority, existing image
entries are not clobbered by subsequent entries.

Images are identified by file paths (n parameters).

Control points are imported anyway even if points already exist in other
projects, duplicates points are however not imported.

=head1 Calling syntax

  ptomerge <pto-file> <pto-file ...> <pto-file>
