 It is useful for filling in forms etc. 
 
-Usage:
+Quick Start:
 - open an existing PostScript document.
 - click anywhere on the document and type a text line.
 - the frame around the text shows, which text line has the focus.

 - reedit text, that has been added with flpsed.

+- lines can be given names ("tags"). The text of these lines can
+  be replaced in batch mode (no X11 required).

 Restrictions:
 - flpsed probably does not work on all existing PostScript documents.
   You simply have to test it for your documents.

+Tags and Batch Mode:
+
+to use batch mode, add text lines to your PostScript document as usual. 
+Give all or some of the lines tag names (Tags->Edit Tag). 
+Save the document. Now you can replace the text of the tagged line in batch
+mode using the -t flag (see usage).
+Example:
+Lets assume you have added text lines with tags "name", and "street"
+to your document letter.ps with flpsed in interactive mode and saved the
+result in letter-templ.ps.
+You can now call flpsed in batch mode to set the actual values:
+
+flpsed -b -t name="Hans Meier" -t street="Haupstr. 14" letter-templ.ps out.ps
