+# General rules: all replacing is in-line. Respect unsupported values, comments
+# and as many spacing as possible.
+
+# The concept of keyword (kw) here is a key, normaly in its own line, whose
+# boolean representation is its own existence.
+
+# A $re is a regular expression. In most functions here, regular expressions
+# are converted to simple separators, by using gst_replace_regexp_to_separator.
+# This makes it easier to convert a parse table into a replace table.
+
+# Every final replacing function to be used by a table must handle one key
+# at a time, but may replace several values from there.
+#
+# Return 0 for success, and -1 for failure.
+#
+# Most of these functions have a parsing counterpart. The convention is
+# that parse becomes replace and split becomes join:
+# gst_parse_split_first_str -> gst_replace_join_first_str
+
+# Additional abstraction: replace table entries can have
+# arrays inside. The replace proc will be ran with every
+# combination that the arrays provide. Ex:
+# ["user", \&gst_replace_foo, [0, 1], [2, 3] ] will replace
+# using all possibilities in the combinatory of [0, 1]x[2, 3].
+# Check RedHat 7.2's network replace table for further
+# enlightenment.
