+.SH NAME
+dtaus \- Converter for DTAUS files
+.SH DESCRIPTION
+The
+.BR dtaus (1)
+program reads and writes German DTAUS files. DTAUS is an acronym for
+.BR D aten T räger AUS tausch.
+It is used by German credit institutes in order to implement money
+exchanges between accounts and credit institutes. These files are
+always called
+.IR dtaus0.txt .
+
+Since they are shipped in a weird ascii format that is not quite
+readable and writable for humans a special control format was
+implemented. The
+.BR dtaus (1)
+program reads and writes such a control file and generates a proper
+DTAUS file if requested.
+
+.SH "CONTROL FILE"
+The control file implements a very simple format. Empty lines and
+those beginning with a hash (`#') mark are ignored. The remaining
+file is splitted into three major parts: one BEGIN record, several
+regular records and one optional END record, which is ignored when the
+file is read but is extracted from the
+.I dtaus0.txt
+file.
+
+Here's a short sample for a control file:
+
+ BEGIN {
+ Art LK
+ Name Martin Schulze
+ Konto 123545
+ BLZ 2004002
+ }
+
+ {
+ Transaktion Einzug
+ Name Martha Schulze
+ Konto 98832
+ BLZ 2004003
+ Betrag 20.00
+ Zweck Gebühr Wohnheimnetz
+ Text Anschluß u. 11+12.97
+ }
+
+ ...
+
+German Umlauts are converted on the fly so you don't need to care
+about them. Since the
+.I dtaus0.txt
+file only uses uppercase letters every text is also converted to
+uppercase.
+
+Except for the way records are delimited the format should be self
+explanatory.
+
+.SH "SEE ALSO"
+DTAUS files use a special but simple and freely documented format.
+It is included in the distribution of dtaus as
+.IR dtaus.txt .
