* WIP: Introducing the LSCP shell: for now, providing color
  highlighting while typing (indicating correct part bold white,
  incorrect part red, and turning green when the command is
  complete. The shell application is implemented as thin client,
  that is the parser work is performed on sampler side and the
  shell application is just providing output formatting.
* Bumped version (1.0.0.svn28).

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.
