-options are given, directory headings are omitted and
-each file is shown in full (with its containing directory);
-.B -d
-causes directories to be listed;

-.TH MATHCALC 1
-.SH NAME
-mathcalc \- interface to a TclLib calculator module
-.SH SYNOPSIS
-.B mathcalc
-.SH DESCRIPTION
-.I Mathcalc
-reads simple expressions from the standard input, evaluates them,
-and prints the results on the standard output.
-It is a command line interface to a
-.L TclLib
-calculator module.
-It prompts the user
-.RL ( calc% )
-for each line, and
-exits on end-of-file or on reading a line containing
-.RB ` quit '.
-.PP
-Values are either integer or floating-point constants.
-A floating-point constant has a decimal point, an exponent, or both.
-Integer constants are taken as hexadecimal if they start
-.BR 0x ,
-octal  if they start with
-.BR 0 ,
-and otherwise decimal.
-.PP
-Expressions are formed using the following C-like operators
-and predefined functions, shown in order of decreasing priority:
-.TP
-.B - + ! ~
-unary: negate, plus (no-op); logical not and one's complement (integers only)
-.TP
-.B * / %
-multiply and divide, integer remainder
-.TP
-.B + -
-add, subtract
-.TP
-.B << >>
-left shift, right shift (integers only)
-.TP
-.B < <= >= >
-relational operators
-.TP
-.B == !=
-equality, inequality
-.TP
-.B &
-bit-wise and (integer only)
-.TP
-.B ^
-bit-wise exclusive-OR (integer only)
-.TP
-.B |
-bit-wise or (integer only)
-.TP
-.B &&
-logical and
-.TP
-.B ||
-logical or
-.TP
-.IB a ? b : c
-conditional: if
-.I a
-is non-zero, the result is
-.IR b ,
-otherwise
-.I c
