        !             2: .SH NAME
        !             3: ucache \- List and remove objects in the Application cache
        !             4: .SH SYNOPSIS
        !             5: .B ucache
        !             6: .SH DESCRIPTION
        !             7: After being downloaded, the program
        !             8: .I ucache
        !             9: will cache itself as a global command and exits.
        !            10: The user can access the command through the \fBMore\fR
        !            11: submenu under the item \fIucache\fR displayed with a garbage
        !            12: can icon. An arrow from the item directs the user to a 
        !            13: submenu that lists sequentially all objects (commands and
        !            14: applications) that are currently in the terminal's Application
        !            15: cache.
        !            16: .PP
        !            17: The names listed in the \fIucache\fR submenu are the
        !            18: \fImenu names\fR of the objects. Menu names are names that
        !            19: cached applications use to advertise themselves in the
        !            20: \fBMore\fR menu. They may be different from \fItag names\fR
        !            21: which uniquely identify an object in the Application cache.
        !            22: (For further discussion, see \fIcache(3L)\fR.) If an
        !            23: object in the Application cache does not have a menu name,
        !            24: its tag name is displayed instead.
        !            25: .PP
        !            26: Items in the \fIucache\fR submenu may be greyed. Greyed
        !            27: items mean they cannot be selected for removal because:
        !            28: .IP "\f3\(em\f1"
        !            29: they have been cached with the \fBA_PERMANENT\fR bit set
        !            30: (see \fIcache(3L)\fR). In this case, the item names are
        !            31: displayed with a lock icon, and they can never be uncached
        !            32: by \fIucache\fR.
        !            33: .ce
        !            34: \f3or\f1
        !            35: .IP "\f3\(em\f1"
        !            36: they have been requested (used) by some running process.
        !            37: If all processes using the object exit or are deleted, then the
        !            38: item's name corresponding to the object will be un-greyed.
        !            39: .PP
        !            40: Items that are not greyed can be selected for removal. All caching 
        !            41: information concerning the object will be erased and the memory freed.
        !            42: Note that \fIucache\fR can remove itself from the Application cache.
        !            43:
