=head1 NAME

gram-ga.pl - Command-line interface to An GramadE<oacute>ir

=head1 SYNOPSIS

B<gram-ga.pl> [I<options>] [I<FILE>...]

=head1 DESCRIPTION

This script checks the grammar of Irish language input
I<FILE>s (or standard input if no files are named).  The default behavior 
is to write a summary of possible errors to standard output.

=head1 OPTIONS

=over 4

=item B<-a>, B<--all>,
    B<--iomlan>     

report all errors (i.e. do not use ~/.neamhshuim)

=item B<-f>, B<--incode>,
    B<--ionchod>=I<ENC>

specify the character encoding of the text to be checked

=item B<-t>, B<--outcode>,
    B<--aschod>=I<ENC> 

specify the character encoding for output

=item B<--interface>,
    B<--comheadan>=xx

choose the language for error messages

=item B<--color>, B<--colour>,
    B<--dath>=I<COLOR> 

specify the color to use for highlighting errors

=item B<-l>, B<--list>,
    B<--litriu>     

write misspelled words to standard output

=item B<--moltai>,
    B<--aspell>     

suggest corrections for misspellings

=item B<-o>, B<--output>,
    B<--aschur>=I<FILE>

write output to I<FILE>

=item B<-h>, B<--cabhair>,
    B<--help>       

display this help and exit

=item B<-v>, B<--leagan>,
    B<--version>    

output version information and exit


=item B<--api>        

output a simple XML format for use with other applications

=item B<--html>       

produce HTML output for viewing in a web browser

=item B<--no-unigram>

do not resolve ambiguous parts of speech by frequency

=item B<--xml>        

write tagged XML stream to standard output, for debugging


=back

=head1 FILES

If there are words you wish to be ignored by the grammar checker
(proper names, etc.) you can place them in a file called I<.neamhshuim>
in your home directory, one word per line.

=head1 REQUIRES

Perl 5.8, Lingua::GA::Gramadoir
