 Still, the documentation generates well, and at least gives a clue about object usage.

+## Bindings
+
+SWE-GLib utilizes [GObject Introspection](https://wiki.gnome.org/GObjectIntrospection), which means it is available for many languages. Check out the [examples](examples) directory for some sample code!

 ## Usage

 Many functions return non-opaque C structs; their documentation can be found inline, and in the generated GTK-Doc. Unless otherwise stated, the returned values should never be freed.

-### Initialization
-
-First of all, you have to initialize the library:

-```c
-gswe_init();

 ### Creating the required objects

 Then you need to create a `GsweTimestamp` object:

 ### Fixed stars are not known yet

 Although Swiss Ephemeris has the functionality to calculate the position of fixed stars, SWE-GLib doesn't provide such functionality. This, however, is a planned feature for the close future.

+## Licencing
+
+As the underlying Swiss Ephemeris is published under GPL (or a commercial license I can not afford), SWE-GLib is also uses that. This means that you can currently use SWE-GLib in software published under the GNU GPL v3.

+# We support a fairly large range of possible variables.  It is expected that all types of files in a test suite
+# will belong in exactly one of the following variables.
+#
+# First, we support the usual automake suffixes, but in lowercase, with the customary meaning:
+#
+#   test_programs, test_scripts, test_data, test_ltlibraries
+#
+# The above are used to list files that are involved in both uninstalled and installed testing.  The
+# test_programs and test_scripts are taken to be actual testcases and will be run as part of the test suite.
+# Note that _data is always used with the nobase_ automake variable name to ensure that installed test data is
+# installed in the same way as it appears in the package layout.
+#
+# In order to mark a particular file as being only for one type of testing, use 'installed' or 'uninstalled',
+# like so:
+#
+#   installed_test_programs, uninstalled_test_programs
+#   installed_test_scripts, uninstalled_test_scripts
+#   installed_test_data, uninstalled_test_data
+#   installed_test_ltlibraries, uninstalled_test_ltlibraries
+#
+# Additionally, we support 'extra' infixes for programs and scripts.  This is used for support programs/scripts
+# that should not themselves be run as testcases (but exist to be used from other testcases):
+#
+#   test_extra_programs, installed_test_extra_programs, uninstalled_test_extra_programs
+#   test_extra_scripts, installed_test_extra_scripts, uninstalled_test_extra_scripts
+#
+# Additionally, for _scripts and _data, we support the customary dist_ prefix so that the named script or data
+# file automatically end up in the tarball.
+#
+#   dist_test_scripts, dist_test_data, dist_test_extra_scripts
+#   dist_installed_test_scripts, dist_installed_test_data, dist_installed_test_extra_scripts
+#   dist_uninstalled_test_scripts, dist_uninstalled_test_data, dist_uninstalled_test_extra_scripts
+#
+# Note that no file is automatically disted unless it appears in one of the dist_ variables.  This follows the
+# standard automake convention of not disting programs scripts or data by default.
+#
+# test_programs, test_scripts, uninstalled_test_programs and uninstalled_test_scripts (as well as their disted
+# variants) will be run as part of the in-tree 'make check'.  These are all assumed to be runnable under
+# gtester.  That's a bit strange for scripts, but it's possible.

Gergely Polonkai (W00d5t0ck)	551ea4cee0	Add missing documentation gswe_antiscion_data_new_with_planets() and gswe_antiscion_data_calculate() were not documented, nor exposed to the public API as they should be.	2013-10-09 00:05:38 +02:00
Gergely Polonkai	fa1b4574e4	Add package version requirement GLib 2.32.0 is now required. Every recent distribution ships with at least 2.32.0 now.	2013-10-05 03:05:22 +02:00
Gergely Polonkai	bd8c1532e7	Protect gswe_init() from re-entry As gswe_init() calls functions that call gswe_init(), gswe_init() must be protected against such re-entry.	2013-10-05 03:04:03 +02:00
Gergely Polonkai (W00d5t0ck)	367b777a2d	Initialize SWE-GLib from each class init function This is to satisfy #8. Also, this makes SWE-GLib available for GLib before 2.36, as gswe_init() also calls g_type_init(), which was necessary before GLib 2.36	2013-10-05 02:18:30 +02:00
Gergely Polonkai (W00d5t0ck)	695f5b96ae	Initialize GLib type system when necessary With 2.36 it became deprecated, as the type system is initialized automatically. Before that version, just call g_type_init() from gswe_init()	2013-10-05 02:11:12 +02:00
Gergely Polonkai (W00d5t0ck)	dd803b09f2	Create own autogen.sh gnome-autogen.sh can not really make GTK-Doc optional. With this script, GTK-Doc is only used if it is actually present on the system.	2013-10-05 02:05:17 +02:00
Gergely Polonkai (W00d5t0ck)	74cc121221	Fix script in Travis CI configuration The default C script uses make test, but we have make check instead	2013-10-05 01:24:52 +02:00

Gergely Polonkai (W00d5t0ck)	5f8939d730	Make gswe_error_quark() available to glib < 2.34	2013-10-05 01:12:09 +02:00
Gergely Polonkai (W00d5t0ck)	7463b0e5cd	Patch autogen.sh to make GTK-Doc really optional • gnome-autogen.sh does’t recognize the need for GTK-Doc if GTK_DOC_CHECK is not present at the beginning of a line of configure.ac (which is the case here) • autogen.sh now takes care of running gtkdocize, thus copying over gtk-doc.make. If GTK-Doc is not present, a fake gtk-doc.make is generated, so automake doesn’t complain anymore	2013-10-05 00:57:38 +02:00
Gergely Polonkai (W00d5t0ck)	e0893de2d2	Make GTK-Doc Makefile creation conditional If GTK-Doc is not present, they cannot be generated at all…	2013-10-05 00:00:48 +02:00
Gergely Polonkai (W00d5t0ck)	371c123f17	Add gnome-common to Travis CI configuration With removing GTK-Doc as a dependency, it is not installed any more – however, it is badly needed by autogen.sh	2013-10-04 23:53:26 +02:00
Gergely Polonkai (W00d5t0ck)	95f085ea0a	Make GTK-Doc optional If it is not installed on the system, that should not be a problem anymore	2013-10-04 23:46:00 +02:00
Gergely Polonkai (W00d5t0ck)	35a8101c91	Update Travis CI configuration Disabling GTK-Doc call, as Travis Linux doesn't include GTK-Doc 1.19 yet	2013-10-04 23:43:20 +02:00

Gergely Polonkai (W00d5t0ck)	c2a0b6bada	Add test case for GsweTimestamp This can be run with make check. Other tests are to follow	2013-10-04 23:37:36 +02:00
