* NKSP: Implemented built-in script function "inc()".
* NKSP: Implemented built-in script function "dec()".
* NKSP language fix: division expressions were evaluated too often.
* NKSP language fix: string concatenation operator was right
  associative instead of left (to right).
* Bumped version (2.0.0.svn15).

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.
