-===== Changes ===== 
  
-Changes from original somFree compiler: 
- 
-  * Most of internal structures now also present as in old IBM SOM 2.1 NT Toolkit. 
-  * New emitters: 
-    * LNK - Open Watcom WLink support. 
-    * DUMP - displays structures, available to emitter. 
-    * PAS - Pascal client support. 
-    * IPAS - Pascal implementation classes support. 
-  * SOM Compiler library now mostly documented. 
-  * SOMLINK style functions for most of SOM Compiler library added. 
-  * Emitters now IBM SOM 2.1 and IBM SOM 3.0 compatible without recompilation. 
-  * somFree Compiler supports IBM SOM 2.1, IBM SOM 3.0, and somFree 1.0 emitters. 
-  * somtShowEntry function outputs more info. 
-  * Undocumented SOMTTypes now documented. 
-  * SOMIPC now supports IDL 4.2 specification. 
-  * CORBA C Language Mapping Specification 1.0 now supported by default instead of CORBA 1.1 C Language mapping. 
-  * Added support of OIDL files
