NAME
     dtappgather - gather application files for  presentation  by
     the Application Manager

SYNOPSIS
     [ -r ]

DESCRIPTION
     The Application Manager presents personal, system, and fac-
     tory applications in an easy-to-access window.  The Applica-
     tion Manager is implemented as a special File Manager view
     of a subdirectory that is built on a per-user, per-session
     basis.  The dtappgather utility is responsible for creating
     and refreshing the user's Application Manager subdirectory.

     The dtappgather utility is run at login and whenever the
     user invokes the ReloadApps action.  The user's individual
     subdirectory for the Application Manager,
     /var/dt/appconfig/appmanager/$DTUSERSESSION, is opened when
     the user presses the Application Manager control on the
     Front Panel.

     The sequence of events is as follows:

        o       When the user logs in, the Xsession script
                sources in the Xsession.d script that sets the
                DTUSERSESSION environment variable.

        o       Xsession then invokes the dtsearchpath utility to
                set the DTAPPSEARCHPATH environment variable.

        o       After dtsearchpath returns with the DTAPPSEAR-
                CHPATH assembled, the Xsession script calls
                dtappgather.

        o       As its main function, dtappgather traverses the
                DTAPPSEARCHPATH, examining each possible source
                of applications and, where there are existing
                source subdirectories, creates symbolic links
                between the source and the user's DTUSERSESSION
                subdirectory.

        o       Finally, dtappgather turns off write permissions
                on the resulting subdirectory to ensure its
                integrity.

                A similar sequence occurs when the user double-
                clicks the ReloadApps action after logging in.

                Although the value of the DTAPPSEARCHPATH can be
                modified in a local shell, the Application
                Manager view based on its value is not functional
                until you log out and log back in.  Since this
                can be a tedious venture, you can verify the
                Application Manager view by executing dtsear-
                chpath(1) and dtappgather in the local shell.
                For example, to add host trout as a system-wide
                application server, set the dtsearchpath(1) input
                environment variable, DTSPSYSAPPHOSTS:

                DTSPSYSAPPHOSTS=trout:

                Then, execute dtsearchpath(1) to update the
                DTAPPSEARCHPATH environment variable.

                eval `dtsearchpath`

                Finally, gather the new applications by executing
                dtappgather.  The Application Manager will show
                the new application groups but will not be func-
                tional.

OPTIONS
     The -r option causes dtappgather to retain the previous con-
     tents of the Application Manager, although discarding broken
     links.  At login, dtappgather destroys the user's previous
     DTUSERSESSION subdirectory before creating a new one.  At
     ReloadApps time, the -r option is used to minimize visual
     disruption of any opened Application Manager views.

RETURN VALUES
     The command always returns 0 (zero) for successful comple-
     tion.

ENVIRONMENT
        DTAPPSEARCHPATH
                       Set by the dtsearchpath(1) utility.
                       DTAPPSEARCHPATH controls the places where
                       dtappgather will gather applications.  The
                       default locations consist of
                       $HOME/.dt/appmanager (for end users),
                       /etc/dt/appconfig/appmanager/$LANG (for
                       system administrators), and
                       /usr/dt/appconfig/appmanager/$LANG (for
                       factory applications).

        DTUSERSESSION  Controls the location of the end user's
                       subdirectory where the Application Manager
                       will be rooted.  The subdirectory name
                       includes both the user's $LOGNAME and
                       $DISPLAY in order to ensure the user's
                       view of the Application Manager remains
                       consistent across sessions.

LOCALES
     When searching for system administrator and factory default
     Application Manager files, dtappgather always uses a value
     of $LANG equal to C.  When the user picks a language at
     login, the corresponding $LANG subdirectories are searched.
     If multiple $LANG subdirectories exist in
     /etc/dt/appconfig/appmanager, all $LANG subdirectories will
     appear in the Application Manager; however, if multiple
     $LANG subdirectories exist in /usr/dt/appconfig/appmanager
     then the language-specific subdirectory based on the current
     value of $LANG is chosen instead of the C subdirectory.

     Regardless of locale, all the action files that exist under
     the user's $HOME/.dt/appmanager subdirectory will be symbol-
     ically linked to the user's Application Manager subdirec-
     tory.

FILES
        /usr/dt/bin/Xsession
                       Among its tasks at login, the Xsession
                       script invokes dtsearchpath(1), and then
                       dtappgather.

        /var/dt/appconfig/appmanager/$DTUSERSESSION
                       This subdirectory is where dtappgather
                       assembles the Application Manager view for
                       the particular user and CDE session.

NOTES
     In the case of multiple search locations having the same
     name, dtappgather picks only the first and discards the
     rest.  For example, if the system administrator sets
     DTSPSYSAPPHOSTS=tuna:,trout:
     and if both hosts, tuna and trout, have an
     /etc/dt/appconfig/appmanager/C/Editors folder, then only the
     Editors folder from tuna (the first host) will appear in the
     user's Application Manager.

     After building the user's DTUSERSESSION, dtappgather turns
     off write permissions on that subdirectory to disallow
     alteration by the end user.  Although the end user can
     resize the window and rearrange the icons within the window,
     the Application Manager is intended to be a read-only source
     of local and networked applications.
