The value of the icon search path
(XMICONSEARCHPATH and XMICONBMSEARCHPATH) is created by assembling
the following locations, listed in order of precedence:
Locations specified using the DTSPUSERICON variable
Locations derived from the DTSPUSERAPPHOSTS variable
The default personal location: HomeDirectory/.dt/icons
The default location: /etc/dt/appconfig/icons/language
Locations specified using the DTSPSYSICON variable
Locations derived from the DTSPSYSAPPHOSTS variable
/usr/dt/appconfig/icons/language
The color and monochrome search paths differ only in the precedence
given to pixmap and bitmaps. The XMICONSEARCHPATH variables lists pixmaps before bitmaps; XMICONBMSEARCPATH lists bitmaps before pixmaps.
