    *  Name:

    *  Purpose:
    *     Copies values from an AST KeyMap to a primitive HDS object.

    *  Language:
    *     C.

    *  Invocation:
    *     void atlKy2hd( AstKeyMap *keymap, HDSLoc *loc, int *status )

    *  Description:
    *     This routine copies the contents of an AST KeyMap into a supplied
    *     HDS structure.

    *  Arguments:
    *     keymap
    *        An AST pointer to the KeyMap.
    *     loc
    *        A locator for the HDS object into which the KeyMap contents
    *        are to be copied. A new component is added to the HDS object for
    *        each entry in the KeyMap.
    *     status
    *        The inherited status.

    *  Name:
    *     ReadOneTable

    *  Purpose:
    *     Reads a single Table from a text file.

    *  Description:
    *     This function reads text from the supplied file descriptor until it
    *     reaches the end of file or encounters an end-of-table marker (a line
    *     consisting just of two or more minus signs with no leading spaces).
    *     It creates an AstTable from the text and returns a pointer to it.

    *  Arguments:
    *     fd
    *        The file descriptor.
    *     fname
    *        The file name - used for error messages.
    *     iline
    *        Pointer to an int holding the number of lines read from the
    *        file so far. Updated on exit to include the lines read by the
    *        invocation of this function.
    *     status
    *        Pointer to the global status variable.

    *  Returned Value:
    *     A pointer to the Table read from the file, or NULL if an error occurs.

void kpg1Kygp1( AstKeyMap *keymap, Grp **igrp, const char *prefix,
                int *status ){
/*
*+
*  Name:
*     kpg1Kygp1

*  Purpose:
*     Creates a GRP group holding keyword/value pairs read from an AST KeyMap.

*  Language:
*     C.

*  Invocation:
*     void kpg1Kygp1( AstKeyMap *keymap, Grp **igrp, const char *prefix,
*                     int *status )

*  Description:
*     This function is the inverse of kpg1Kymp1. It extracts the values
*     from the supplied AST KeyMap and creates a set of "name=value" strings
*     which it appends to a supplied group (or creates a new group). If
*     the KeyMap contains nested KeyMaps, then the "name" associated with
*     each primitive value stored in the returned group is a hierarchical
*     list of component names separated by dots.

*  Arguments:
*     keymap
*        A pointer to the KeyMap. Numerical entries which have bad values
*        (VAL__BADI for integer entries or VAL__BADD for floating point
*        entries) are not copied into the group.
*     igrp
*        A location at which is stored a pointer to the Grp structure
*        to which the name=value strings are to be appended. A new group is
*        created and a pointer to it is returned if the supplied Grp
*        structure is not valid.
*     prefix
*        A string to append to the start of each key extracted from the
*        supplied KeyMap. If NULL, no prefix is used.
*     status
*        Pointer to the inherited status value.

*  Notes:
*     - This function provides a private implementation for the public
*     KPG1_KYGRP Fortran routine and kpg1Kygrp C function.
*     - Entries will be stored in the group in alphabetical order
