Package FESI.jslib Description
Contains the public routines to access FESI
objects and functions. They are patterned after
Netscape 3.x functions and are largely upward
compatible with them (but greatly extended).
The routines wrap the native FESI objects
and delegate the operations. This allow a better
independence of the implementation of FESI from
these routines, at the cost of some overhead.
