+# 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

+#   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:
