Handle the class field in the role_transition rule. If no class is
specified, then it would be set to the "process" class by default.

I'd just add the long --help option to the man page for completeness:

This patch is proposed to solve Ticket #1 [1672486] (command line
binaries should support --version and --help).
It adds handling of -h, -V and the long formats --help and --version to
all binaries (checkpolicy/checkmodule).
It also adds handling of long options for some of the available options.
Manual pages have also been updated accordingly (and a few undocumented
options have been documented).

The boundry format mapped the primary field to a boolean in the
properties bitmap. This is appropriate for the kernel policy, but in
modular policy the primary field may be an integer that indicates the
primary type that is being aliased. In this case, the primary value cannot
be assumed to be boolean.
This patch creates a new module format that writes out the primary value
as was done before the boundry format.

This looks like a bug in policy_scan.l - we are not escaping (via
backslash) special characters in the pattern and thus the "-" (dash) is
being interpreted rather than taken literally. The same would seemingly
apply for "." (dot), and would seem relevant not only to PATH but also
for IDENTIFIER. The patch below seems to fix this issue for me:
