\&\fBdealer.dpp\fR [\fIinputfile\fR]
.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
dealer.dpp stands for dealer-pre-processor. Its main purpose it to preprocess
input files for Hans van Staveren's great dealer program.
.SH "SYNTAX"
.IX Header "SYNTAX"
The program expands shape specifications of the form:
.PP
.Vb 1
\&    shape{COMPASS, shp1 + shp2 + ... + shpM \- shm1 \- ... \- shmN}
.Ve
.SS "regular shapes"
.IX Subsection "regular shapes"
7xxx, 4432, 4xx5 have the same meaning as in original dealer.
.SS "the `at least' operator"
.IX Subsection "the `at least' operator"
whenever you put a `+' after a suit-length, it means `at least'.
.PP
.Vb 3
\&    shape{north, 5+xx5+}: at least 5/5 in the blacks,
\& \-\->shape(north,5xx5 + 5xx6 + 6xx5 + 5xx7 + 6xx6 + 7xx5 + 5008 + 6007
\&                + 7006 + 8005)
.Ve
.SS "the `at most' operator:"
.IX Subsection "the `at most' operator:"
same as the `at least', just use a `\-':
.PP
.Vb 2
\&    shape{north, 2\-xxx}: at most 2 spades,
\& \-\->shape(north,0xxx + 1xxx + 2xxx)
.Ve
.SS "the `range' operator:"
.IX Subsection "the `range' operator:"
the range operator operates on a single suit. It comes with [],
like in Perl.
.PP
.Vb 2
\&    shape{north, x[3\-5]x[13]}: (3 to 5) hearts, and one or 3 clubs 
\& \-\->shape(north,x3x1 + x4x1 + x3x3 + x5x1 + x4x3 + x5x3)
.Ve
.PP
Note that shape{north, 3\-xxx} is equivalent to shape{north,[0\-3]xxx}
You can write compound ranges if you want:
.PP
.Vb 1
\&    shape{north, [013\-68]xxx} means: 0,1,3,4,5,6 or 8 spades.
.Ve
.SS "the `permutation' operator:"
.IX Subsection "the `permutation' operator:"
the permutation operator will appears as () like in the \s-1WBF\s0 rules
of specifying shapes.
.PP
.Vb 2
\&    shape{north, (4432)}: any 4432 hand.
\& \-\->shape(north,any 4432)
.Ve
.PP
what's best is that the () operator can operate on restricted groups
of cards:
.PP
.Vb 2
\&    shape{north, 5s(431)}: 5 spades, the others suits being (431).
\& \-\->shape(north,5134 + 5314 + 5143 + 5341 + 5413 + 5431)
.Ve
.PP
What you have to do is:
.IP "\(bu" 4
specify the suit names (s,h,d,c in english) in the left part of
the shape, in any order,
.IP "\(bu" 4
and enclose the rest of the permutation into () in the right part.
.PP
A (complicated) example:
.PP
.Vb 3
\&    shape{north, 4+c3+d(2+2+)}: at least 5 clubs, at least 3 diamonds, 
\&                               and no short major.
\& \-\->shape(north,3334 + 4234 + 2434 + 3244 + 2344 + 2254 + 3235 + 2335 + 2245 + 2236)
.Ve
.SS "the `Major' operator:"
.IX Subsection "the `Major' operator:"
has to be used together with the () operator. `M' stands for `a major'
The `M' operator can only be used in the left part (never put a M
inside the parens)
.PP
.Vb 2
\&    shape{north, 5M(xxx)}
\& \-\->shape(north,x5xx + 5xxx)
\&
\&    shape{north, 5+M3+c(31)}
\& \-\->shape(north,1534 + 3514 + 1633 + 3613 + 5134 + 5314 + 6133 + 6313)
.Ve
.SS "the `minor' operator:"
.IX Subsection "the `minor' operator:"
same as the `Major' operator, but in lowercase `m'.
.PP
.Vb 2
\&    shape{north, 5M5m(xx)}
\& \-\->shape(north,x5x5 + 5xx5 + x55x + 5x5x)
.Ve
.SS "the `conditional' operator:"
.IX Subsection "the `conditional' operator:"
you've got the possibility of specifying complex conditions to be
verified that cannot be simply expressed by other operators. In
order  to do that, you use the `:' operator, just after the
atomic-shape specification:
.PP
.Vb 1
\&    shape{north, shp1:condition1,condition2,...}
.Ve
.PP
The conditions use the letters (s,h,d,c) as variables for the suit
lengths, and the usual C\-operators (*,+,\-,/,>,<,==,!,?, and so on).
Note that the `,' stands for the `and\-logical' operator. You can
use `or' for the `or\-logical' operator.
.PP
.Vb 2
\&    shape{north, 4+s4+h(xx):d>c,h+s==10}
\& \-\->shape(north,6421 + 6430 + 5521 + 5530 + 4621 + 4630)
