          DO NOT DELETE AAS_BASE.SDZ UNDER ANY CIRCUMSTANCES!

------------------------------------------------------------------------

To upgrade from Absolute Annihilation 2.1 or later, just drop the update
SDZ files into your Spring\Mods directory.  Do not delete AAS_Base.sdz
unless you intend to completely uninstall the mod - all versions of AA
from 2.1 onward require this file in order to function.

How the patching works:

AAS_Base.sdz contains the basic data set upon which all versions of AA
from 2.1 onward require.  All mutators draw information from this file.
The new file, AASP[version].sdz overrides anything in AAS_Base.sdz which
has become outdated, but the vast majority of the data will always be
needed, such as buildpics, unit scripts, textures, and so on.

You can, however, delete the other SDZ files without any risk, examples:
    AASA21.sdz - can be deleted
    AASB21.sdz - can be deleted
    AASF21.sdz - can be deleted
    AASH21.sdz - can be deleted
    AASS21.sdz - can be deleted
 AASP[version] - can be deleted

You should not delete the most recent version of the above files though.
Doing so may prevent you from playing AA or any of its "mutators".

  AAS_Base.sdz - must not be deleted unless you intend to fully remove
                 AA from your system
