The name of the manual page, or \(em in particular in section 1, 6, |

|
the manual page. |
|
When first invoked, the |

macro expects a single argument, the name of the manual page. |
|
Usually, the first invocation happens in the |

section of the page. |
|
The specified name will be remembered and used whenever the macro is |
|
called again without arguments later in the page. |

macro uses |
