The version of CAMERON in WinGX has been slightly modified so that it is more useful as a graphical editor, as well as a structure visualisation tool. It retains the full functionality of the "official" release. When the command "END" is issued, CAMERON will write out a modified .INS file (called name.OUT) which will contains all the atoms which were in the last picture. Atoms which have been "EXCLUDED" will not appear in this file, while atoms "RENAMED" will have the new name.
CAMERON comes with its own detailed manual (CAMERON.PS) in PostScript format, which is supplied with the WinGX package. It is installed in the WinGX manuals directory.
