NAME
ua - user agent configuration files
DESCRIPTION
The user agent configuration files in the directory / usr /lib/ ua
may be used by other programs. Since these files direct the
actions of the user agent, they are protected against inadvertent
modification. The files can be changed only by super user editing
them in ed (or whatever) or by programmatic changes (e.g., an
install or remove script).
The configuration files are:
Suffixes
Office
Ad ministration
Preferences
Environment
Comm_pkgs
Defines file types and default
actions on files.
Defines initial office objects and
their default actions.
Defines initial administration
objects.
Defines initial objects for which
preferences can be set.
Defines environment variables.
Provides access to emulator applications
through the phone
manager.
All the files use a keyword = value syntax. The keyword is
always at the beginning of a line, and a newline terminates the
value. White space surrounding the keywords is ignored, as are
empty lines. Keyword matches are case sensitive, and when an
undefined keyword is found, the line is ignored.
To insert a comment, start the line with a pound sign ( # ).
To define new objects or environment variables, add files of these
names in your home directory. User definitions add to the system
definitions, and where conflicts occur, the user definitions override
the system definitions.
The filenames begin with an upper case letter so that they will
appear first in directory listings.
Objects and Actions
Except for Environment, all the files define objects for the user
agent and the legal actions (commands) that can be performed on
them. The commands for any object must be taken from the set
of user agent commands (see below).
Before any objects are defined, the user agent knows about two
classes of objects, files and menu objects, and about the commands
that operate on them.
The file objects class includes all UNIX files. Initially, there are
three objects defined in the files class: directories, executable files,
and files.
