Detailed Description

Here the interfaces to the outside are defined - environment variables and similar.

#define DIFF_ENV "FSVS_DIFF"

The diff program to use.

It's arguments are similar to

   diff -u file1 --label1 file2 --label2

If you use another program, expect these parameters.

An exit status of 1 is ignored; the meaning "file has changed" is assumed.
