[Cartoweb-users] Problem ini file parsing and question aboutswitches

as far I as know how the childrenswitching system work, it switchs layers 
(or layerGroups), not mapfiles
if only generate one mapfile, but give the layers an additional id 
corresponding to a selected switch

after discussing a bit with one of my colleague, the only way you have is to 
"duplicate" your projects and set in each a different mapfile
then you can use the project switcher menu to change easily from one to 
see the "Choose project" menu in http://www.cartoweb.org/demos/client.php
name it "Choose mapfile" and the users wont notice they effectively change 
of project

to make things easier, one can certainly imagine to have the file of the 
projects "copies" to simply use symbolic links to the original project, with 
just the few different files in hard, like layers.ini and the mapfile
or use a automated deploying/copying script to generate the project copies
