13    # The following is the libtool / shared library version. This doesn't have to
14    # do anything with the release version. It MUST conform to the following rules:
15    #
16    #  1. Start with version information of `0:0:0' for each libtool library.
17    #  2. Update the version information only immediately before a public release of
18    #     your software. More frequent updates are unnecessary, and only guarantee
19    #     that the current interface number gets larger faster.
20    #  3. If the library source code has changed at all since the last update, then
21    #     increment revision (`c:r:a' becomes `c:r+1:a').
22    #  4. If any interfaces have been added, removed, or changed since the last update,
23    #     increment current, and set revision to 0.
24    #  5. If any interfaces have been added since the last public release, then increment
25    #     age.
26    #  6. If any interfaces have been removed since the last public release, then set age
27    #     to 0.

1133                                  This int->float conversion might hurt on some systems.
1134                                intmathabs:
1135                                  Similar to intmath but uses abs() function.
1136                                  Depending on compiler and platrofm this could
1137                                  perform better than integer math as it avoids
1138                                  an extra integer multiply instruction.
1139                                diharmonic:
1140                                  The triangular wave will be approximated by adding two
1141                                  sinusoidials. This solution might especially hurt on
