=head1 NAME
Demeter::Plugins::SpecFileLongLine - Deal with SPEC files with a very long column label line
=head1 VERSION
This documentation refers to Demeter version 0.9.26.
=head1 SYNOPSIS
This plugin cleans up a SPEC file that has a column label line -- the one
with C<#L> -- that is too long for the hard-wired string length in Ifeffit.
=head1 Methods
=over 4
=item C<is>
The C<is> method is used to identify the file type by noticing a C<#L>
line that is longer than 254 characters.
=item C<fix>
This cleans up the file by simply copying every line except the
troublesome one.
