 * where xxx stands for your displays hostname(s)

 *

 * display related configuration:

 *   first do some common setup, then try to figure out

"*

 * define extensions for image files (i.e. extension-to-readerClass

 * mappings). Some of the readers are autoloaded (see patches file).

 * Moved this from code to here (from Image-class), for more flexibility

 * actually since this is not display- but host specific (naming conventions)

 * it should be moved into the host.rc or h_xxx.rc file

 *

 * Some readers are optional and therefore, only installed if the

 * corresponding Smalltalk class is nonNil; not accessing it as global,

 * but via a SMalltalk>>at: message - this avoids warning messages

 * during startup, if classes are missing and the globals are undefined.
