 * @class SBMLStripPackageConverter
 * @sbmlbrief{core} Converter that removes SBML Level 3 packages.
 *
 * @htmlinclude libsbml-facility-only-warning.html
 *
 * This SBML converter takes an SBML document and removes (strips) an SBML
 * Level&nbsp;3 package from it.  No conversion is performed; the package
 * constructs are simply removed from the SBML document.  The package to be
 * stripped is determined by the value of the option @c "package" on the
 * conversion properties.
 *
 * @section SBMLStripPackageConverter-usage Configuration and use of SBMLStripPackageConverter
 *
 * SBMLStripPackageConverter is enabled by creating a ConversionProperties
 * object with the option @c "stripPackage", and passing this properties
 * object to SBMLDocument::convert(@if java ConversionProperties@endif).
 * This converter takes one required option:
 *
 * @li @c "package": the value of this option should be a text string, the
 * nickname of the SBML Level&nbsp;3 package to be stripped from the model.
 *
 * In addition, the converter understands an additional optional:
 *
 * @li @c "stripAllUnrecognized": if set to @c true, the converter will
 * remove all SBML Level&nbsp;3 package constructs for Level&nbsp;3 packages
 * that this copy of libSBML does not recognize.  Note that what a given copy
 * of libSBML recognizes is determined by which plug-ins it has been
 * configured to include.  If this option is enabled, it may remove SBML
 * Level&nbsp;3 package constructs that are legitimate in the sense that they
 * are officially defined SBML constructs, but not recognized because the
 * running copy of libSBML has not had support enabled for them.
