+.SH DESCRIPTION
+.IX Header "DESCRIPTION"
+This module provides four global hashes:
+.PP
+.Vb 4
+\&    %B::Op_private::bits
+\&    %B::Op_private::defines
+\&    %B::Op_private::labels
+\&    %B::Op_private::ops_using
+.Ve
+.PP
+which contain information about the per-op meanings of the bits in the
+op_private field.
+.ie n .SS %bits
+.el .SS \f(CW%bits\fP
+.IX Subsection "%bits"
+This is indexed by op name and then bit number (0..7). For single bit flags,
+it returns the name of the define (if any) for that bit:
+.PP
+.Vb 1
+\&   $B::Op_private::bits{aelem}{7} eq \*(AqOPpLVAL_INTRO\*(Aq;
+.Ve
+.PP
+For bit fields, it returns a hash ref containing details about the field.
+The same reference will be returned for all bit positions that make
+up the bit field; so for example these both return the same hash ref:
+.PP
+.Vb 2
+\&    $bitfield = $B::Op_private::bits{aelem}{5};
+\&    $bitfield = $B::Op_private::bits{aelem}{6};
+.Ve
+.PP
+The general format of this hash ref is
+.PP
+.Vb 5
+\&    {
+\&        # The bit range and mask; these are always present.
+\&        bitmin        => 5,
+\&        bitmax        => 6,
+\&        bitmask       => 0x60,
+\&
+\&        # (The remaining keys are optional)
+\&
+\&        # The names of any defines that were requested:

+\&        bitcount_def  => \*(AqOPpFOO_BITS\*(Aq,
+\&
+\&        # If present, Concise etc will display the value with a \*(AqFOO=\*(Aq
+\&        # prefix. If it equals \*(Aq\-\*(Aq, then Concise will treat the bit
+\&        # field as raw bits and not try to interpret it.

+\&        # If present, specifies the names of some defines and the

+\&        # lar integer values within the bit field; e.g. 3 is dis\-
+\&        # played as \*(AqC\*(Aq.

+\&
+\&    };
+.Ve
+.ie n .SS %defines
+.el .SS \f(CW%defines\fP
+.IX Subsection "%defines"
+This gives the value of every \f(CW\*(C`OPp\*(C'\fR define, e.g.
+.PP
+.Vb 1
+\&    $B::Op_private::defines{OPpLVAL_INTRO} == 128;
+.Ve
+.ie n .SS %labels
+.el .SS \f(CW%labels\fP
+.IX Subsection "%labels"
+This gives the short display label for each define, as used by \f(CW\*(C`B::Concise\*(C'\fR
+and \f(CW\*(C`perl \-Dx\*(C'\fR, e.g.
+.PP
+.Vb 1
+\&    $B::Op_private::labels{OPpLVAL_INTRO} eq \*(AqLVINTRO\*(Aq;
+.Ve
+.PP
+If the label equals '\-', then Concise will treat the bit as a raw bit and
+not try to display it symbolically.
+.ie n .SS %ops_using
+.el .SS \f(CW%ops_using\fP
+.IX Subsection "%ops_using"
+For each define, this gives a reference to an array of op names that use
+the flag.
