I really like meld as a visual diff tool, but I wanted to have have it show multiple comparisons at once from the commandline. In the GUI, you can create multiple tabs for multiple comparisons, but there is (was) no way to do it directly from the command line. So, I wrote a patch that lets you use it like this:

meld spam.orig spam.mine - eggs.orig eggs.mine - pants.orig pants.mine

The usage is the same as it was before, but now you can specify multiple comparisons, separated by “-”. We’ll see if the patch is accepted; I posted it to the mailing list. In the meantime, you can download it here.
