# GF web-based syntax editor
John J. Camilleri
January 2013
A tool for building and manipulating abstract syntax trees in GF.
This is meant as improved replacement of the [old syntax editor][old].
[old]:http://www.grammaticalframework.org/~meza/restWiki/editor.html
## Example usage
If you want to use the tool in your own application, everything you need in the source
files `editor.html` and `editor_online.js`. Contact the [GF developer mailing list][gf-dev]
if you have any problems.
[gf-dev]:http://groups.google.com/group/gf-dev
