Extensions

Extensions are additional functions, usually developed in C or Fortran, which extend the core functionality of LME. Extensions are grouped in so-called dynamically-linked libraries (DLL) files. At startup, LME loads all extensions it finds in the folder LMEExt in the same location as the LME program file. Each extension initializes itself and usually displays a line of information in the Command window. No further action is needed in order to use the new functions.

Note that the current release includes some extensions inside the EXE application itself.

You can also develop and add your own extensions, as explained in the next chapter.

Here is the list of the extensions currently provided with LME for Pocket PC.
