    A Permuted Index for CSPICE APIs
    ===========================================================================

       This document is an index for NAIF's CSPICE functions. The index entries
       are short phrases that describe the functionality of the functions.
       Each phrase is followed by the name of the function that performs the
       described function.

       The reason we call this a ``permuted'' index is that each index
       entry occurs in multiple (cyclic) permutations, allowing each
       significant word in every functional description of a function to
       occur first in at least one index entry. For example, the function
       pxform_c (which returns the matrix that transforms position vectors
       from one specified frame to another at a specified epoch) can be
       found under the entries

          FIND a position transformation matrix                      pxform_c
          MATRIX, find a position transformation                     pxform_c
          POSITION transformation matrix, find a                     pxform_c
          TRANSFORMATION matrix, find a position                     pxform_c

       Some descriptions map to multiple functions; this happens when there
       are functions that perform the same function on different data
       types.

       This index is alphabetically ordered by the index entries.
