The Vend::Options::Matrix module implements matrix product options for
Interchange. It is compatible with Interchange 4.8.x matrix options.
If the Interchange Variable MV_OPTION_TABLE is not set, it defaults
to options, which combines options for Simple, Matrix, and
Modular into that one table. This goes along with foundation and
construct demos up until Interchange 4.9.8.
The options table remains the default for matrix options.
