-- ## FAQ
--
-- You can enter the project directory firstly before building project.
--
--   $ cd projectdir
--
-- 1. How to build project?
--
--   $ xmake
--
-- 2. How to configure project?
--
--   $ xmake f -p [macosx|linux|iphoneos ..] -a [x86_64|i386|arm64 ..] -m [debug|release]
--
-- 3. Where is the build output directory?
--
--   The default output directory is `./build` and you can configure the output directory.
--
--   $ xmake f -o outputdir
--   $ xmake
--
-- 4. How to run and debug target after building project?
--
--   $ xmake run [targetname]
--   $ xmake run -d [targetname]
--
-- 5. How to install target to the system directory or other output directory?
--
--   $ xmake install
--   $ xmake install -o installdir
