=head1 NAME
physics-unit - Helper script for the Physics::Unit Perl module
=head1 SYNOPSIS
  physics-unit meters            # Returns information about the unit 'meters'
  physics-unit -e                # Exports lists of units as HTML
  physics-unit --help/-h         # Shows a usage message
=head1 DESCRIPTION
L<Physics::Unit> is a Perl module for managing units and unit conversions. The C<physics-unit> script retrieves unit and type information from the main module for reference purposes. Do not use this script from your code, use the L<Physics::Unit> module instead. This script's interface is subject to change, the main module's API is much more stable.
=head1 OPTIONS AND ARGUMENTS
  physics-unit [options] [name(s)|expression(s)]
  If reserved words, unit or type names, or unit expressions, are given on the
  command line, this prints a block of information for each to STDOUT.  The
  options -e, -t, and -u, on the other hand, cause comprehensive lists of
  data to be dumped from the unit library.
  -e
  --export
      Export a complete list of known units and types as HTML documents.
      Prints the names of the created files to STDOUT, this allows:
        firefox `physics-unit -e`
  -h
  --help
      Shows a usage message and exits. Overrides all other options.
  -t
  --types
      Print a list of types (one per line) to STDOUT.
  -u
  --units
      Print a list of units (one per line) to STDOUT.
