Why I don't want to write editor for the preferences.

    First of all, the IceWM is my favorite window manger.
It is small, light, quick and has many features.
You can tune it by many options.
    Preferences are main options' file for the IceWM. There
are many various options in this file. That's why an editor
for this file will be the complex program. IMHO, the best 
editor for it is vim. You can find any option in vim with
/-command. This file well documented and you can understand
the aim of any option. Into special editor searching will be
not so easy. But some options, such as colors or fonts, better
to edit with visual tools. I have written small tool for choosing
colors and fonts and vim's macros for calling this tool.
