Summary description: Mathematical tools to use with amsmath

Announcement text: ----------------------------------------------------------------------

For mathtools.dtx v1.29

* In section `Special mathtools options` clearified when `gathered` of pure amsmath might give a warning. (#38) * Added 3.6 note 3: about section{foo $ orm[ig]{bar}$}. * Renamed a few colon combo symbols and added a few extra for completeness. (#44) A package option is available to revert the change. * Added a warning if mathtools is loaded *after* `unicode-math` (#43)

Please note that this is a **breaking** change! For many years mathtools have provided some colon related symbols, like :=. The names of which was copied from txfonts/pxfonts. It turned out that these names were inconsistent, for example coloneq would be :- where as coloneqq would be :=. This has now been changes such that both provides :=. Additional colon symbols have also been added. If needed, the package option legacycolonsymbols will revert the old behaviour of coloneq, Coloneq, eqcolon and Eqcolon.
