********************************************************************************************
  The 'merge' command has now been deprecated as the same functionality can be achieved by
  performing the following tasks:

  origen compile [COMPILE DIRECTORY/FILE] -r [DIRECTORY/FILE FOR COMPARISON]

  By using the -r switch, it overrides the default reference directory which origen uses,
  therefore essentially allowing origen to diff between your output directory and any directory
  of your choice (for example ASCII UTIL export directory)

The reverse of 'origen compile' to help merge any changes made to compiled files back to the source.
The arguments are the same as the compile command, so run the merge with the same arguments and it will merge instead of compile.
Changes are processed as follows:
* Any files with a non-erb source are simply copied back if they have changes.
* Any files that don't have a source copy are ignored.
* Any differences in files with an ERB source are left to the user to resolve. Origen tries to help by giving you the
  commands to execute to show the differences and the files that must be edited.

Usage: origen merge [space separated files, lists or directories] [options]
