-# This is a sample RocksDB options file, modified from RocksDB Performance
-# Tuning Guide for a typical configuration.
+# This is a RocksDB option file.
+#
+# A typical RocksDB options file has four sections, which are
+# Version section, DBOptions section, at least one CFOptions
+# section, and one TableOptions section for each column family.
+# The RocksDB options file in general follows the basic INI
+# file format with the following extensions / modifications:
+#
+#  * Escaped characters
+#    We escaped the following characters:
+#     - \n -- line feed - new line
+#     - \r -- carriage return
+#     - \\ -- backslash \
+#     - \: -- colon symbol :
+#     - \# -- hash tag #
+#  * Comments
+#    We support # style comments.  Comments can appear at the ending
+#    part of a line.
+#  * Statements
+#    A statement is of the form option_name = value.
+#    Each statement contains a '=', where extra white-spaces
+#    are supported. However, we don't support multi-lined statement.
+#    Furthermore, each line can only contain at most one statement.
+#  * Sections
+#    Sections are of the form [SecitonTitle "SectionArgument"],
+#    where section argument is optional.
+#  * List
+#    We use colon-separated string to represent a list.
+#    For instance, n1:n2:n3:n4 is a list containing four values.
+#
+# Below is an example of a RocksDB options file:
