+ (description "This package provides solutions to a number of common
+difficulties in writing displayed equations and getting high-quality output.
+The single most ambitious goal of the package is to support automatic
+linebreaking of displayed equations. Such linebreaking cannot be done without
+substantial changes under the hood in the way formulae are processed; the code
+must be watched carefully, keeping an eye on possible glitches. The bundle
+also contains the @code{flexisym} and @code{mathstyle} packages, which are
+both designated as support for @code{breqn}.")
