"""Represent a file's status.

Instance variables:

file -- the filename (no slashes), None if uninitialized
    lseen -- true if the data for the local file is up to date
    eseen -- true if the data from the CVS/Entries entry is up to date
             (this implies that the entry must be written back)
    rseen -- true if the data for the remote file is up to date
    proxy -- RCSProxy instance used to contact the server, or None

Note that lseen and rseen don't necessary mean that a local
    or remote file *exists* -- they indicate that we've checked it.
    However, eseen means that this instance corresponds to an
    entry in the CVS/Entries file.

If lseen is true:

lsum -- checksum of the local file, None if no local file
    lctime -- ctime of the local file, None if no local file
    lmtime -- mtime of the local file, None if no local file

If eseen is true:

erev -- revision, None if this is a no revision (not '0')
    enew -- true if this is an uncommitted added file
    edeleted -- true if this is an uncommitted removed file
    ectime -- ctime of last local file corresponding to erev
    emtime -- mtime of last local file corresponding to erev
    extra -- 5th string from CVS/Entries file

If rseen is true:

rrev -- revision of head, None if non-existent
    rsum -- checksum of that revision, Non if non-existent

If eseen and rseen are both true:

esum -- checksum of revision erev, None if no revision
