=head1 USAGE

    idealize-ali.pl <infiles> [optional arguments]

Path to input ALI files [repeatable argument].

=for Euclid: infiles.type: readable
    repeatable

=back

=head1 OPTIONAL ARGUMENTS

=over

=item --max[-res-drop-site]=<n>

Number of non-gap character states allowed in a site to be dropped [default:
0]. When specified as a fraction between 0 and 1, it is interpreted as
relative to the number of sequences in the ALI. By default, only shared gaps
are dropped.

=for Euclid: n.type:    number
    n.default: 0

=item --out[-suffix]=<suffix>

Suffix to append to infile basenames for deriving outfile names [default:
none]. When not specified, outfile names are taken from infiles but original
infiles are preserved by being appended a .bak suffix.

=for Euclid: suffix.type: string
