-# Release lvgl, lv_examples, lv_drivers. docs, blog and prepare the development of the next major, minoror bugfix release
-# Usage: ./release,py bugfix | minor | major
-# The option means what type of versin to prepare for development after release
-#
-# STEPS:
-#  - clone all 5 repos
-#  - get the version numnber from lvgl.h
-#  - set release branch (e.g. "release/v7")
-#  - prepare lvgl
-#    - run lv_conf_internal.py
-#    - run code formatter 
-#    - clear LVGL_VERSION_INFO (set to "")
-#    - run Doxygen 
-#    - update the version in lvgl's library.json, library.properties, lv_conf_template.h
-#    - update CHANGELOG.md
-#    - commit changes 
-#  - prepare lv_examples
-#    - upadte the required LVGL version in lv_examples.h (LV_VERSION_CHECK) 
-#    - update the version in lv_ex_conf_template.h
-#  - prepare lv_drivers
-#    - update the version in library.json, lv_drv_conf_template.h      
-#  - prepare docs
-#    - update API XML 
-#    - clear the versiopn info (should be plain vx.y.z)
-#  - tag all repos with the new version
-#  - merge to release branches
-#  - blog: add release post
-#  - push tags and commits
-#  - docs: run ./updade.py release/vX
-#
-# If --patch
-#  - merge master to dev branches
-#  - increment patch version by 1 and append "-dev". E.g. "vX.Y.(Z+1)-dev"
-#  - update version numbers in lvgl and docs
-#  - commit and push
-#  - docs: run ./updade.py latest dev
-#
-# Else (not --patch)
-#  - merge master to dev  
-#  - merge the dev to master
-#  - increment version number like "vX.(Y+1).0-dev"
-#  - apply the new version in dev branches of lvgl, lv_examples, lv_drivers, docs
-#  - commit and push to dev branches
-#  - docs: run ./updade.py latest dev
