+# Babel does not support paths containing parent directory (..) in mapping files.
+# Because of that if you need path including directories higher in tree that your pwd you need the root.
+# So babel.cfg located in mentat components are templates that are filled with absolute paths to its respective jinja files and python files in mentat packages.
+# cut is used to remove slash from begging of path returned by realpath because babel needs path as relative to its input directory.
 #
 # Alternative solution that uses the hawat-cli utility:
 #   APP_ROOT_PATH=$(shell realpath ./chroot) hawat-cli intl init $(INIT_LOCALE)
