SciTE in the minimum configuration require just one file to work, the main executable (I'm speaking about Windows, but SciTE exists for Linux, MacOSX, and whatever OS you want).
SC174.exe The current release at moment of this writing
If you want get more from SciTE, you can use this files that I have writed for you.
[SCiTEGlobal.properties]
[Pipmak.api]
These files must be putted in the same directory/folder of the main application.
I need contribution to improve these files! At the moment I am not managed to activate the auto-indentation, but I know which the thing it's possible, because it work with other language, like "C++".
If you want change menus language, you can add also locale.properties downloadable from http://scintilla.sourceforge.net/SciTETranslation.html .
