PEBundle is a utility that physically attaches win32 DLLs and other files to executables by one of two methods. The advanced bundling technique allows for some DLLs to be bound to the executable without ever writing the DLL back to the disk. The other, simpler method allows one to bundle and compress file(s) with an executable and have those file(s) extracted to disk at runtime. PE Bundle can prevent the need to use an installer program to copy.
