The Ia32/Ipf/X64 binaries of EdkShellBinPkg are generated with EFI shell project (svn r63) and build with Edk Compatibility & BaseTools Package (r12898). The binaries are built with no debug information by building with "RELEASE" target.

The following steps can help to re-generate these binaries for customization:
1. Check out EdkCompatibilityPkg (r12898) to $(WORKSPACE)\EdkCompatibilityPkg (svn https://svn.code.sf.net/p/edk2/code/trunk/edk2/EdkCompatibilityPkg).
2. Check out EdkShellPkg (r12898) to $(WORKSPACE)\EdkShellPkg (svn https://svn.code.sf.net/p/edk2/code/trunk/edk2/EdkShellPkg).
3. Check out Edk Shell project source (r63) to $(WORKSPACE)\Shell (svn https://svn.code.sf.net/p/efi-shell/code/trunk/Shell). 
4. Check out BaseTools (r12898) to $(WORKSPACE)\BaseTools (svn https://svn.code.sf.net/p/edk2/code/trunk/edk2/BaseTools).
5. Under $(WORKSPACE) directory (i.e. c:\EdkII),
   To generate Minimum Shell, execute: "build -a IA32 -a X64 -a IPF -p EdkShellPkg\EdkShellPkg.dsc -m Shell\Shell.inf -b RELEASE".
   To generate Full Shell, execute: "build -a IA32 -a X64 -a IPF -p EdkShellPkg\EdkShellPkg.dsc -m Shell\ShellFull.inf -b RELEASE".
6. In EdkShellBinPkg\Bin, we only provides the binary files of those applications which haven't been contained in Minmum Shell but in Full Shell.
   To generate them, execute: "build -a IA32 -a X64 -a IPF -p EdkShellPkg\EdkShellPkg.dsc -m Shell\XXX\*.inf -b RELEASE". XXX means the corresponding module name.


The Arm binaries of EdkShellBinPkg are generated with EFI shell project (svn r61) and build with Edk Compatibility & BaseTools Package (r13646).
