A minor ‘character’ issue with the exclude-pages statement when there is only one page to exclude;

   exclude-pages on [4] 

and a number of similar arrangements (without the brackets for example) results in the following error at compile time;

   making atlas ... D:\Program Files\Therion\therion.exe: error -- Invalid character in the exclusion list!

The solution is to add a comma;

   exclude-pages on [4,]
