=head1 NAME

tmx2tmx - utility to convert and filter TMX files

=head1 SYNOPSYS

  tmx2tmx -cat file1.tmx ... filen.tmx > file.tmx

  tmx2tmx -toTrados file1.tmx > file2.tmx

  tmx2tmx -clean file1.tmx > file2.tmx

  tmx2tmx -select=PT,EN multilingual.tmx > pt-en.tmx

=head1 DESCRIPTION

This utility processes TMX documents and return TMX documents. Tasks
done with this utility include conversion between TMX versions and TMX
cleaning.

=head2 TRADOS conversion

As you maybe know, TRADOS is a company producing computer software for
translators. It includes WorkBench which imports TMX
files. Unfortunately, the version I used do not import TMX version
1.4.

This process is done using the switch C<-toTrados>:

  tmx2tmx -toTrados file.tmx > trados.tmx

=head2 TMX Cleaning

Specially when translation memories are created from anotated text, or
extracted directly from the Internet using any automatic method. This
switch is used to remove junk in translation units.

This option tries to remove junk from TMX files, like empty pairs
where one of the sides is empty, or removing other junk type.

Use it this way:

   tmx2tmx -clean file.tmx > file2.tmx

=head2 Concatenating TMX

   tmx2tmx -cat file1.tmx ... filen.tmx > file.tmx
   ls | grep '.tmx$' | tmx2tmx -cat > file.tmx

=head2 Select languages

Select a bunch of languages:

    tmx2tmx -select=PT,EN,FR huge.tmx > pt-en-fr.tmx

clean()    if $clean;
