# 1. /FluidDoc will be used as the workspace of PaddlePaddle/docs. 
# 2. And /docs is used as the output of doc-build process.
# 3. If conflicted with yours, please modify the definition of FLUIDDOCDIR and
#    OUTPUTDIR in the subsequent codes.
# 4. The doc-build process is controlled under EnvVar BUILD_DOC and UPLOAD_DOC.
#    All the Chinese and English docs will be generated, and then uploaded.
