/!\ reorganize all the file hierarchy, move the code and launching script to src: - browser_side --> src/browser - public --> src/browser_side/public - libervia.py --> src/browser/libervia_main.py - libervia_server --> src/server - libervia_server/libervia.sh --> src/libervia.sh - twisted --> src/twisted - new module src/common - split constants.py in 3 files: - src/common/constants.py - src/browser/constants.py - src/server/constants.py - output --> html (generated by pyjsbuild during the installation) - new option/parameter "data_dir" (-d) to indicates the directory containing html and server_css - setup.py installs libervia to the following paths: - src/common --> <LIB>/libervia/common - src/server --> <LIB>/libervia/server - src/twisted --> <LIB>/twisted - html --> <SHARE>/libervia/html - server_side --> <SHARE>libervia/server_side - LIBERVIA_INSTALL environment variable takes 2 new options with prompt confirmation: - clean: remove previous installation directories - purge: remove building and previous installation directories You may need to update your sat.conf and/or launching script to update the following options/parameters: - ssl_certificate - data_dir
