RM/COBOL File Conversion

\Documents\Micro Focus\Visual COBOL\Samples\Convert_ACU_and_RM_Files_to_MF\rm2mf\Readme.xml says "This utility converts an RM/COBOL indexed file or directory of files to Micro Focus indexed files. The RMMFDataMigration.exe and RM2MFconvert.dll executables can be used as delivered, or the source can be modified and rebuilt as desired."

I got the solution to compile and convert a file, but I'm having trouble finding the source. Where is the source for RM2MFconvert.dll and inxconvert.cob?
