Add option to make the changes directly in the input file

[mlauritse]

An option like "--modify", to indicate that the input file should be modified directly (inspired by "tidy") would be useful.

It is of course possible to do this by having cssembed write to a temporary file and then replacing the input file by the temporary file, but this is a bit clumsy and error-prone.

Thanks for a great utility!

I think you can do this by specifying the same input and output file. I'll double-check.

This is old, but felt like chiming in.

Nicholas is correct, if you specify the same input & output file name cssembed will overwrite the original file.
