# OpenEmbedded source checksums checker

# source archive are the same as the one used to generate checksums.
#
# Run it:
#
# oe-source-checker.py path-to-conf/checksums.ini path-to-sources

#
# How to deal with output:
#
# 1. download each failed entry
# 2. check md5 and sha256 of file
# 3. correct checksums.ini if needed
# 4. share changes
