## Declaring math versions

`\DeclareMathVersion` `{`<version>`}`

Defines <version> to be a math version. The newly declared version is initialised with the defaults for all symbol fonts and math alphabets declared so far (see the commands `\DeclareSymbolFont` and `\DeclareMathAlphabet`). If used on an already existing version, an information message is written to the transcript file and all previous `\SetSymbolFont` or `\SetMathAlphabet` declarations for this version are overwritten by the math alphabet and symbol font defaults, i.e. one ends up with a virgin math version. Example:

       \DeclareMathVersion{normal}
