This is a module to check the filesystem for the presence and
permissions of certain files. It can also be used to correct the
permissions (but not existance) of those files.
Currently only supports Posix systems (with Posixy permissions).
Permission stuff can probably be stubbed out later.

Reads a spec like 'rw-r--r--' into a octal number suitable for
chmod. That is characters in groups of three -- first group is
user, second for group, third for other (all other people). The
characters are r (read), w (write), and x (executable), though the
executable can also be s (sticky). Files in sticky directories
get the directories permission setting.
Examples::
>>> print oct(read_perm_spec('rw-r--r--'))
0644
>>> print oct(read_perm_spec('rw-rwsr--'))
02664
>>> print oct(read_perm_spec('r-xr--r--'))
0544
>>> print oct(read_perm_spec('r--------'))

Gives the difference between the actual mode of the file and the
given mode. If ``keep_exe`` is true, then if the mode doesn't
include any executable information the executable information will
simply be ignored. High bits are also always ignored (except
suid/sgid and sticky bit).

Calculates the new mode given the current node ``cur_mode`` and
the mode spec ``mode`` and if ``keep_exe`` is true then also keep
the executable bits in ``cur_mode`` if ``mode`` has no executable
bits in it. Return the new mode.

Calculates what a string spec means, returning (uid, username,
gid, groupname), where there can be None values meaning no
preference.
The spec is a string like ``owner:group``. It may use numbers
instead of user/group names. It may leave out ``:group``. It may
use '-' to mean any-user/any-group.

Represents a set of specifications for permissions.
Typically reads from a file that looks like this::
rwxrwxrwx user:group filename
If the filename ends in /, then it expected to be a directory, and
the directory is made executable automatically, and the contents
of the directory are given the same permission (recursively). By
default the executable bit on files is left as-is, unless the
permissions specifically say it should be on in some way.
You can use 'nomodify filename' for permissions to say that any
permission is okay, and permissions should not be changed.
Use 'noexist filename' to say that a specific file should not
exist.
Use 'symlink filename symlinked_to' to assert a symlink destination
The entire file is read, and most specific rules are used for each
file (i.e., a rule for a subdirectory overrides the rule for a
superdirectory). Order does not matter.
