LyX is a fully featured document processor that encourages an approach to writing based on the structure of your documents (WYSIWYM) and not simply their appearance (WYSIWYG).
This is the development version of LyX. Please do not use this version of LyX for any serious work.
If you find a bug in this LyX development version, please go to https://www.lyx.org/trac and open a new ticket with the version marked as the appropriate "dev" version and specify that you used rollApp to test.
