+JTSDK DLL Qt MinGW/MSYS2 Supplementary Notes
+==============================================================
+
+This assumes you have an environment set up that conforms with 
+instructions in the WSJT-X Install notes that will build Hamlib 
+
+Before you start.... RTFM at <hamlib-base>/scripts/README.build-Windows-JTSDK.txt
+
+
+1. Update Environ
+=================
+
+pacman -Syuu
+
+
+2. Deploy MinGW
+===============
+
+Ensure that the ZIP, DOS2UNIX and GROFF packages are deployed 
+to and owrking in the MSYS2 Environment
+
+pacman -S zip
+pacman -S dos2unix
+alias unix2dos='todos'
+pacman -S groff
+
+The next step is possibly redudnant as it has been incorporated
+into build-w64-jtsdk.sh
+
+export PATH=$PATH:$GCCD_F:.
+
+
+3. Create a dir $HOME/Builds
+============================
+
+Open a MSYS2 Terminal fro a jtsdk64.ps1 environment 
+
+In a JTSDK63 ENvironment type: 
+
+msys2
+
+In the msys2 enviro nment type:
+
+cd ~		<== ensure you at home
+mkdir builds
+cd builds
+
+
+4. Locate and unzip LibUSB matching version deployed above into builds
+======================================================================
+
+These steps in the original build-w64.sh script are redundant.
+
+You may skip this step.
+
+JTSDK 3.2.0 (and later) points the environment to the libusb 
+deployment in X:\JTSDK64-Tools\tools\libusb through 
+environment variable $libusb_dir_f .
+
+If you need the source for LinUSB use steps similar to those
+below to obtain source:  
+
+wget https://sourceforge.net/projects/libusb/files/libusb-1.0/libusb-1.0.24/libusb-1.0.24.tar.bz2
+tar -xvf libusb-1.0.24.tar.bz2
+
+[ This creates a subdirectory libusb-1.0.24 ]
+
+
+5. Obtain latest Hamlib sourceforge
+===================================
+
+git clone git://git.code.sf.net/p/hamlib/code hamlib-4.2~git
+
+
+6. Start the Process Rolling
+============================
+
+cd ./hamlib-4.2~git
+./bootstrap			       <== Not included in Nate's notes !
+./scripts/build-w64-jtsdk.sh hamlib-4.2~git
+
+
+7. Tadaa - Drumroll !
+=====================
+
+==> Package in ~/build/hamlib-4.2~git/hamlib-w64-4.2~git as hamlib-w64-4.2~git.zip
+==> Headers in ~/build/hamlib-4.2~git/hamlib-w64-4.2~git/include
+==> Library in ~/build/hamlib-4.2~git/hamlib-w64-4.2~git/lib/gcc as libhamlib.dll.a (rename to libhamlib.dll for application)
