| | | version-name |
Defines version-name to be a math version. Initializes this version with the default for all symbol fonts declared so far (see | |). Internally stores the stuff in |@|version-name.
If used on an already existing version, a warning is issued and all previous | | declarations for this version are overwritten by the symbol font defaults, i.e. one ends up with a virgin math version.
Example: \DeclareMathVersion{normal}
