+QPM27
+-----
+
+QPM is not available in source form.  In this folder, you will find
+qcp27.dat and qdos27.dat.  These are the CCP and BDOS components for
+QPM.  They were created by running QINSTALL on a normal RomWBW
+CP/M 2.2 system, then extracting the resultant CCP and BDOS binaries.
+
+When this folder goes through the build process, it just combines the
+QPM CCP and BDOS binaries with the RomWBW CBIOS to create an up-to-date
+QPM system image.
+
+QPM 2.7 is distributed at https://www.microcodeconsulting.com/.
