Here is a new version. Please mind: language keys have changed:
e -> English
d -> Dutch
g -> German

#!/usr/bin/perl -w

=head1 NAME

tran - show translations for context commands and keywords

=head1 SYNOPSIS

	tran en|ne|ed|de|nd|dn command-name_or_keyword...

	tran en|ne|ed|de|nd|dn <file_containing_commnds_or_keywords

=head1 DESCRIPTION

B<tran>, given one or more context command names or keywords, or a
file (on standard input) containing those, B<tran> prints each of them
with its translation on standard output. The source language and the
target language are given with the first parameter,
which must be a key consisting of two letters, one for the source
language and for the target language. Currently the only allowed
letters are d, e and g for Dutch, English and German.

=head1 EXAMPLES

>From Dutch to English:

        $ tran de taal starttekst hoogte
                            taal -> language
                      starttekst -> starttext
                          hoogte -> height

>From English to German:

        $ tran eg language starttext height
                        language -> sprache
                       starttext -> starttext
                          height -> hoehe

Given a file test.tex, containing:

        \starttekst
        \omlijnd[hoogte=ruim]{Hello world!}
        \stoptekst

you can show the translation for every Dutch context command or
keyword in English with:

        $ tran de <test.tex
                          hoogte -> height
                         omlijnd -> framed
                            ruim -> broad
                      starttekst -> starttext
                       stoptekst -> stoptext

=head1 ENVIRONMENT

All terms and their translations are taken from the files
F<mult-con.tex> and F<mult-con.tex>. These are supposed to reside in
the directory $ENV{TETEXDIR}/temf/tex/context/base.
