+# RMC database bbclass

+
+# rmc_generate_db()
+# $1: a list of directories. Each directory holds directories for a group of
+# boards.
+# $2: path_name of rmc generates database file and records
+#
+# WARNING: content of directory of database file will be removed.
+#
+# Each board directory shall contain a fingerprint file (*.fp) at least, with
+# optional file blob(s) associated to the type of board. If a board directory
+# has no file blob, no record is created for that board.
+#
+# An example of two directories each of which contains two boards for RMC:
+# (All file and directory names are for illustration purpose.)
+#
+# dir_1/
+#     board_1/
+#         board_1_fingerprint.fp
+#         file_1.blob
+#     board_2/
+#         board_2.fp
+# dir_2/

+#         b3.fp

+DESCRIPTION = "RMC project provides a tool and libraries to identify types \
+of hardware boards and access any file-based data specific to the board's \
+type at runtime in a centralized way. Software (clients) can have a generic \
+logic to query board-specific data from RMC without knowing the type of board. \
+This make it possible to have a generic software work running on boards which \
+require any quirks or customizations at a board or product level. \
