 # 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.
+# Sets SOURCE_DATE_EPOCH in each component's build environment.
+# Upstream components (generally) respect this environment variable,
+# using it in place of the "current" date and time.
+# See https://reproducible-builds.org/specs/source-date-epoch/
 #
-# There are 4 ways to determine SOURCE_DATE_EPOCH:
+# After sources are unpacked but before they are patched, we set a reproducible value for SOURCE_DATE_EPOCH.
+# This value should be reproducible for anyone who builds the same revision from the same sources.
 #
-# 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
+# There are 4 ways we determine SOURCE_DATE_EPOCH:
 #
-# If the file does not exist, first try to determine the value for SOURCE_DATE_EPOCH:
+# 1. Use the 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.
+#    Alternatively, it can be provided by a recipe via SRC_URI.
 #
-# 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.
+# If the file does not exist:
+#
+# 2. If there is a git checkout, use the last git commit timestamp.
+#    Git does not preserve file timestamps on checkout.
 #
 # 3. Use the mtime of "known" files such as NEWS, CHANGLELOG, ...
-#    This will work fine for any well kept repository distributed via tarballs.
+#    This works for well-kept repositories distributed via tarball.
 #
-# 4. If the above steps fail, we need to check all package source files and use the youngest file of the source tree.
+# 4. If the above steps fail, use the modification time of the youngest file in 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, ...)
+# Once the value of SOURCE_DATE_EPOCH is determined, it is stored in the recipe's SDE_FILE.
+# If none of these mechanisms are suitable, replace the do_deploy_source_date_epoch task
+# with recipe-specific functionality to write the appropriate SOURCE_DATE_EPOCH into the SDE_FILE.
+#
+# If this file is found by other tasks, the value is exported in the SOURCE_DATE_EPOCH variable.
+# SOURCE_DATE_EPOCH is set for all tasks that might use it (do_configure, do_compile, do_package, ...)
