Overview of changes:

 *  Added saturnin__bug() to help developers help users report bugs
 *  Tweak debug output regarding some globals
 *  Fix document packaging 'doc'
 *  Infrastructure maintenance

The related functionality is stable already and the path is easy to find
out using package manager.

Overview of changes:

 *  Converted to pure shellfu library

    So far we have relied on users embedding Saturnin inside their app
    and updating it by porting changes manually.  This has been awkward
    but was safer for preliminary versions where feature set was not
    stable and separation of the library and the app skeleton has not
    been done properly.

    Nowadays, these problems have been mostly resolved; the feature set
    seems to be stable and the app skeleton has been reduced to only the
    few lines, so it's time to make Saturnin a proper shellfu library.
    Of course, Saturnin can still be embedded, but primary use case is
    to depend on it and import it just as any other shellfu module.

    The 'satcmd' demo app has been moved to a different repo.

 *  Ported conf merge tests from old inigrep

    This was a long-standing debt from the inigrep split.  Tests
    originally created for inigrep have been ported to focus on
    saturnin__conf(), throwing few more in for good measure.

 *  Enabled --help (friendly usage()) in saturnin__conf()

    saturnin__conf() (exposed to user as `myapp conf`) now supports the
    obligatory --help argument.

 *  Did some updates and cleanups.

Move satcmd to other repo and distribute saturnin as a stand-alone
shellfu library.  Users can import just the library instead of
embedding it inside their source tree, which enables them to delegate
part of the job to package manager.

We're scratching right ear with left hand...

 *  Fixed bug that prevernted saturnin_conf queries to contain spaces

Absence of quotes breaks queries with spaces.  We're already taking care
of files (implicit or given on command line).

Overview of changes:

 *  Don't hide short options from usage message and Bash autocomplete
 *  saturnin-conf now has usage message
 *  saturnin-conf now exits with useful status in some scenarios
 *  Hacked completion code together so that updating should be easier
    (command name is set only once)

 *  Cleanup and maintenance

Overview of changes:

 *  Improved help and usage messages

    Small but long wished for change; this may improve ability to
    explore apps easily.

 *  Code clean up and maintenance

Will make code less ugly at places.

Be nicer to people who get help by trial and error.

Overview of changes:

 *  Updated for shellfu 0.9.x

    New shellfu version brings about a lot of changes; this release is
    mostly about catching up with it.

 *  Use predictable meta binary name

    Applications will have updating easier if they use simple generic name
    for meta-command source file; we should set an example (that's the
    point of satcmd, after all).

 *  Minor clean up

The new Shellfu brings some large changes.  Among what touches us
directly:

 *  Most global variables were renamed (removing SHELLFU_* prefix).

 *  inigrep API has been revamped and the file merging/guessing
    feature has been dropped; it now belongs to us.

Overview of changes:

 *  Maintenance release

It's easier to maintain "state of the art" templates by comparing with
peer projects.

subcommand (binary) and its arguments are both already is debug-shown
inside saturnin__runsc; cases when that does not get called are normally
not interesting.

Overview of changes:

 *  Added "last git hash" to application version meta-data (--saturnin-get-*)
 *  Improve meta command template
 *  Build system maintenance

Overview of changes:

 *  Changed default cache path to under .cache subdir
 *  Added --saturnin-get-* for printing Saturnin internal info
 *  Simplified test suite a bit with new TFKit
 *  Enabled Debian packaging
 *  Repo maintenance and cleanup
