TrEd is a graphical editor and viewer of tree structures. It works with files in so called FS-format developed by M. Kren (as a native format for his editor Graph) and used for syntactical and tectogrammatical trees in The Prague Dependency Treebank. Since FS-format is a bit more general, TrEd may surely find other applications as well.

TrEd may be extended by user-defined macros, which are basically functions written in Perl language, with many pre-defined functions for handling FS-trees. Keyboard shortcuts or user-defined menu items may be used to invoke macros.
There is also an non-graphical (off-line) variant of TrEd called btred — which stands for “Batch-mode Tree Editor” — which allows user to run macros on trees without having to enter the graphical interface.
TrEd runs on the following platforms (see Section 2 for details):
Windows 95/98/ME™ or Windows NT/2000/XP™
Linux™
BSD™, UNIX™, Solaris™ and other UNIX-based systems
