+This script calls the first argument for each of the following arguments in
+parallel. E.g.
+parallel.py "clang --opt" file1 file2
+calls
+clang --opt file1
+clang --opt file2
+
+The output (stdout and stderr) is concatenated sequentially in the form:
+______________ file1
+<output of clang --opt file1>
+______________ finish <exit code of clang --opt file1> ______________
+______________ file2
+<output of clang --opt file2>
+______________ finish <exit code of clang --opt file2> ______________
