* extensive synthesis optimization: reimplementation of EGs and LFO(s),
  removed synthesis parameter prerendering and the synthesis parameter
  matrix in general, splitting each audio fragment into subfragments now
  where each subfragment uses constant synthesis parameters
  (everything's still very buggy ATM)

12     # do anything with the release version. It MUST conform to the following rules:
13     #
14     # 1. Start with version information of `0:0:0' for each libtool library.
15     # 2. Update the version information only immediately before a public release of
16     # your software. More frequent updates are unnecessary, and only guarantee
17     # that the current interface number gets larger faster.
18     # 3. If the library source code has changed at all since the last update, then
19     # increment revision (`c:r:a' becomes `c:r+1:a').
20     # 4. If any interfaces have been added, removed, or changed since the last update,
21     # increment current, and set revision to 0.
22     # 5. If any interfaces have been added since the last public release, then increment
23     # age.

25     # to 0.
