LyX
LyX is an WYSIWYM editor for LaTeX documents. It uses its own (text based) format, and allows you to write documents even not knowing LaTeX.
Installation of new LaTeX classes
LaTeX classes (*.cls files) require additional description for LyX which
provide information about presentation of different styles. They are
distributed as *.layout files with optional accompanying *.module files.
Unix systems:
Copy (or symlink) the
*.layoutand*.modulefiles to$HOME/.lyx/layoutsdirectory.
Windows systems:
Copy the
*.layoutand*.modulefiles toC:\Program Files\LyX\Resources\layoutsdirectory.
Start LyX, run Tools –> Reconfigure, and restart the editor.
Goto Tools –> TeX Information and check whether the new classes are available for LyX.
