Quote: "delete needed files"
Well of course.
Let me give you an example for web design.
The 960 grid system (@ 960.gs ) has loads of prebuilt styles in the css, but I have never used all of those styles in a final layout. So I go through and get rid of all the styles I don't use before uploading to the server or sending to a client.
Of course I wouldn't delete files that are needed, but lines of code within files that arent actually being used.
Would be nice if there were an automated way of back referencing the completed map files to the FPSC engine to be able to determine what code was not actually being used.
In this instance, I am sort of referring to the FPSC engine as the css.
