8.10.2 Description and usage

Unitdi scans one or two Free Pascal unit source les and either lists all available identiers, or describes the dierences in identiers between the two units.

You can invoke unitdi with an input lename as the only required argument. It will then simply list all available identiers.

The regular usage is to invoke unitdi with two arguments:

unitdiff input1 input2

Invoked like this, it will show the dierence in interface between the two units, or list the available identiers in both units. The output of unitdi will go to standard output by default.
