mweights – Support for multiple-weight font packages
Many font families available for use with LaTeX are available at multiple weights. Many Type 1-oriented support packages for such fonts re-define the standard \mddefault or \bfdefault macros. This can create difficulties if the weight desired for one font family isn’t available for another font family, or if it differs from the weight desired for another font family.
The package provides a solution to these difficulties.
