+I am making a C++ program that is written in C++ 11 and uses CMake. It is meant for doing calculations for
+bending sheet metal / sheetmetal for pressbrakes, press brakes, brakeforms, breakforms, brake forms, break forms, forming and forming machinery and metalforming machinery and sheetmetal forming machinery.
+
+The /BendCalc folder/directory includes:
+
+CMakeLists.txt  data  docs  include  LICENSE  README.md  src  tests
+
+data is a directcory
+docs is a directory
+include is a directory
+LICENSE is the project license
+README.md is for GitHub
+src is a directory
+tests is a directory
+
+currently data is empty.  this is the place for stored data to and from the machine (using a paralel or serial pot or inputted from the user or saved by this program
+
+docs is the documentation for the BendCalc program in markdown format. it contains 
+
+BendAllowance.md  BendDeduction.md  KFactor.md  Setback.md  Tonnage.md
+
+include contains header files:
+
+BendAllowance.h  DataLoad.h  Deserializer.h  Kfactor.h     Setback.h
+BendDeduction.h  DataSave.h  FormingTool.h   Serializer.h  Tonnage.h
+
+src contains the cpp files:

+BendAllowance.cpp  DataLoad.cpp  Deserializer.cpp  Kfactor.cpp  Serializer.cpp  Tonnage.cpp
+BendDeduction.cpp  DataSave.cpp  FormingTool.cpp   main.cpp     Setback.cpp
+
+main is the entrypoint to the program.  the rest are classes.
