/* ezArchiveTool command line options:

Options to be specific:

-pack "path/to/folder" "path/to/another/folder" ...
-unpack "path/to/file.ezArchive" "another/file.ezArchive"
-out "path/to/file/or/folder"

-pack and -unpack can take multiple inputs to either aggregate multiple folders into one archive (pack)
or to unpack multiple archives at the same time.

-out specifies the target to pack or unpack things to. For packing mode it has to be a file.
The file will be overwritten, if it already exists.
For unpacking the target should be a folder (may or may not exist) into which the archives get extracted.

If no -out is specified, it is determined to be where the input file is located.

If neither -pack nor -unpack is specified, the mode is detected automatically from the list of inputs.
If all inputs are folders, mode is going to be 'pack'.
If all inputs are files, mode is going to be 'unpack'.

Examples:

ezArchiveTool.exe "C:\Stuff"
  will pack all data in "C:\Stuff" into "C:\Stuff.ezArchive"

ezArchiveTool.exe "C:\Stuff" -out "C:\MyStuff.ezArchive"
  will pack all data in "C:\Stuff" into "C:\MyStuff.ezArchive"

ezArchiveTool.exe "C:\Stuff.ezArchive"
  will unpack all data from the archive into "C:\Stuff"

ezArchiveTool.exe "C:\Stuff.ezArchive" -out "C:\MyStuff"
  will unpack all data from the archive into "C:\MyStuff"
