Module name:    gvars3

        src            : GUI.cc 

Log message:
        When reading from a file, lines ending with a single backslash and then 
a newline are treated as continuing on the next line, in the manner of the C 
preprocessor. (No whitespace is allowed after the backslash.)
        If you already have lines ending in a backslash, this will break your 
program; however I hope this is very unlikely.
