+# reproducible_build.bbclass
+#
+# This bbclass is mainly responsible to determine SOURCE_DATE_EPOCH on a per recipe base.
+# We need to set a recipe specific SOURCE_DATE_EPOCH in each recipe environment for various tasks.
+# One way would be to modify all recipes one-by-one to specify SOURCE_DATE_EPOCH explicitly, 
+# but that is not realistic as there are hundreds (probably thousands) of recipes in various meta-layers.
+# Therefore we do it this class. 
+# After sources are unpacked but before they are patched, we try to determine the value for SOURCE_DATE_EPOCH.
+#
+# There are 4 ways to determine SOURCE_DATE_EPOCH:
+#
+# 1. Use value from __source_date_epoch.txt file if this file exists. 
+#    This file was most likely created in the previous build by one of the following methods 2,3,4. 
+#    In principle, it could actually provided by a recipe via SRC_URI
+#
+# If the file does not exist, first try to determine the value for SOURCE_DATE_EPOCH:
+#
+# 2. If we detected a folder .git, use .git last commit date timestamp, as git does not allow checking out
+#    files and preserving their timestamps.
+#
+# 3. Use the mtime of "known" files such as NEWS, CHANGLELOG, ...
+#    This will work fine for any well kept repository distributed via tarballs.
+#
+# 4. If the above steps fail, we need to check all package source files and use the youngest file of the source tree.
+#
+# Once the value of SOURCE_DATE_EPOCH is determined, it is stored in the recipe ${WORKDIR}/source_date_epoch folder
+# in a text file "__source_date_epoch.txt'. If this file is found by other recipe task, the value is exported in
+# the SOURCE_DATE_EPOCH variable in the task environment. This is done in an anonymous python function, 
+# so SOURCE_DATE_EPOCH is guaranteed to exist for all tasks the may use it (do_configure, do_compile, do_package, ...)
