24/**
25 * \file
26 * Auxiliary program for operations on 1D histograms.
27 * The option <tt>-f</tt> corresponds to <tt><file name>:<object name></tt>.
28 *
29 * Possible operations (option <tt>-u <operation></tt>:
30 * - Add\n
31 * ROOT addition of histograms;
32 * - add\n
33 * Addition of histograms by look up of corresponding bin in second histogram;
34 * - Subtract\n
35 * ROOT subtraction of histograms;
36 * - subtract\n
37 * Subtraction of histograms by look up of corresponding bin in second histogram;
38 * - Multiply\n
39 * ROOT multiplication of histograms;
40 * - multiply\n
41 * Multiplication of histograms by look up of corresponding bin in second histogram;
42 * - Divide\n
43 * ROOT division of histograms;
44 * - divide\n
45 * Division of histograms by look up of corresponding bin in second histogram;
46 * - efficiency\n
47 * Like "Divide", but with correction for errors;
48 * - stdev\n
49 * Standard deviation;
50 * - Replace\n
51 * Replace histogram contents by function value;
52 *
53 * If only one histogram is specified, the operation applies to the histogram and the first associated function.\n
54 * Only the quoted ROOT operations and the additional operation Replace are then allowed.\n
55 * The option Replace will replace the histogram contents by the function value.
