(synopsis "Automatic line breaking of displayed equations")
(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}.")
