+# A recapitulation of the format of this file:
+# The file consists of five columns: the name of the op, an English
+# description, the name of the "check" routine used to optimize this
+# operation, some flags, and a description of the operands.
+
+# The flags consist of options followed by a mandatory op class signifier
+
+# The classes are:
+# baseop - 0 unop - 1 binop - 2
+# logop - | listop - @ pmop - /
+# padop/svop - $ padop - # (unused) loop - {
+# baseop/unop - % loopexop - } filestatop - -
+# pvop/svop - "
+
+# Other options are:
+# needs stack mark - m
+# needs constant folding - f
+# produces a scalar - s
+# produces an integer - i
+# needs a target - t
+# target can be in a pad - T
+# has a corresponding integer version - I
+# has side effects - d
+# uses $_ if no argument given - u
+
+# Values for the operands are:
+# scalar - S list - L array - A
+# hash - H sub (CV) - C file - F
+# socket - Fs filetest - F- reference - R
+# "?" denotes an optional operand.
+
# Nothing.
