The package provides a minimal method for making generic (i.e.,
TeX-format-independent) packaged, combining maybeload
functionality, fallback definitions for LaTeX \ProvidesPackage
and \RequirePackage functionality, and handling of arbitrary
(multiple) "private letters" (analagous LaTeX packages' use of
"@") in nested package files. The documentation contains a
central reference for making and using generic packages based
on the package.
