* Set EXAMPLE_CONF_DIR to DOCDIR if DOCDIR gets customizedest312016-03-16
| | | | | | | | | | | | | | | | | | | | | | Before, customisation of DOCDIR did not lead to changes of the EXAMPLE_CONF_DIR default value. This was inconsistent with expected behaviour if you didn't know of the existence of the EXAMPLE_CONF_DIR variable. The confusion is very strong, as (for not in place builds) both DOCDIR and EXAMPLE_CONF_DIR share the same default value, it is unexpected that setting CUSTOM_DOCDIR changes the location of all documentation files but one. The best meaning of EXAMPLE_CONF_DIR is to further allow customization of the mt.conf.example storage place, but otherwise keep defaulting to whatever DOCDIR is set to, at least for not in place builds. This patch implements that behaviour. Fixes #3863.
* Simplify custom games packagingPavel Puchkin2016-01-09

* Fix "make install" and add underscore to doc file nameest312015-09-14
| | | | | | | | Fix regression since commit: 915807f8db1f3721ad9ffc00a4863ad940010c45 "Rename doc/mapformat.txt and update doc to match SRP changes" And add an underscore to doc file name to make it more readable.
* Rename minetest-icon.svg to minetest.svg - Fixes #1564HEXcube2015-09-03
| | | | | | -Complies with the Linux standard freedesktop icon naming specs: http://standards.freedesktop.org/icon-naming-spec/icon-naming-spec-latest.html#guidelines -Ensures compatibility with icon themes -Edit minetest.desktop, CMakeLists.txt and README.md to reflect this change

* Fix a typo in comment of CMakeLists.txtD Laboratory2015-07-18
|
* Make Git version detection use VERSION_STRING instead of tagsShadowNinja2015-05-05
| | | | | | | | | | This fixes the problem where 0.4.12-dev versions were erroneously shown as 0.4.11-dev because the tag was added on a separate branch. It also fixes a similar issue when builders didn't fetch new tags when updating. This also removes the number-of-commits-since-tag field, since it's incompatible with this. Said field doesn't seem to be useful anyway if you have the commit hash.
* Revert the upper-case PROJECT_NAME nonsense that was part of #2402sfan52015-04-27

* Clean up and tweak build systemShadowNinja2015-03-27
| | | | | | | | | | | | | | | | * Combine client and server man pages. * Update unit test options and available databases in man page. * Add `--worldname` to man page. * Fix a bunch of places where `"Minetest"` was used directly instead of `PROJECT_NAME`. * Disable server build by default on all operating systems. * Make `ENABLE_FREETYPE` not fail if FreeType isn't found. * Enable LevelDB, Redis, and FreeType detection by default. * Remove the `VERSION_PATCH_ORIG` hack. * Add option to search for and use system JSONCPP. * Remove broken LuaJIT version detection. * Rename `DISABLE_LUAJIT` to `ENABLE_LUAJIT`. * Rename `minetest_*` variables in `version.{h,cpp}` to `g_*`. * Clean up style of CMake files.
