=head1 NAME
txdcontract - contract a data file by computing the mean over n input rows to produce one output row
=head1 DESCRIPTION
txdcontract n < 100rows.dat > 50rows.dat
A partial bin at the end is dropped. When you choose value-based binning, there
will always be some data dropped at the end. That way, you only get mean values
that actually represent a full interval/bin. Furthermore, the input data is
assumed to be sorted according to the column chosen for value-based binning.
=head1 PARAMETERS
These are the general rules for specifying parameters to this program:
        txdcontract -s -xyz -s=value --long --long=value [--] [files/stuff]
You mention the options to change parameters in any order or even multiple times. They are processed in the oder given, later operations overriding/extending earlier settings. Using the separator "--" stops option parsing
An only mentioned short/long name (no "=value") means setting to 1, which is true in the logical sense. Also, prepending + instead of the usual - negates this, setting the value to 0 (false).
Specifying "-s" and "--long" is the same as "-s=1" and "--long=1", while "+s" and "++long" is the sames as "-s=0" and "--long=0".
There are also different operators than just "=" available, notably ".=", "+=", "-=", "*=" and "/=" for concatenation / appending array/hash elements and scalar arithmetic operations on the value. Arrays are appended to via "array.=element", hash elements are set via "hash.=name=value". You can also set more array/hash elements by specifying a separator after the long parameter line like this for comma separation:
        --array/,/=1,2,3  --hash/,/=name=val,name2=val2
The available parameters are these, default values (in Perl-compatible syntax) at the time of generating this document following the long/short names:
=over 2
=item B<bincol>, B<c> (scalar)
        ''
bin by values in given column instead of contracting by row count
=item B<binsize>, B<b> (scalar)
        1
size of one bin
=item B<black> (scalar)
        0
ignore whitespace at beginning and end of line (disables strict mode) (from Text::NumericData)
=item B<comchar> (scalar)
        undef
comment character (if not set, deduce from data or use #) (from Text::NumericData)
=item B<comregex> (scalar)
        '[#%]*[^\\S\\015\\012]*'
regex for matching comments (from Text::NumericData)
=item B<config>, B<I> (array)
        []
Which configfile(s) to use (overriding automatic search in likely paths);
special: just -I or --config causes printing a current config file to STDOUT
=item B<empty> (scalar)
        0
treat empty lines as empty data sets, preserving them in output (from Text::NumericData)
=item B<fill> (scalar)
        undef
fill value for undefined data (from Text::NumericData)
=item B<help>, B<h> (scalar)
        0
Show the help message. Value 1..9: help level, par: help for paramter par (long name) only.
Additional fun with negative values, optionally followed by comma-separated list of parameter names:
-1: list par names, -2: list one line per name, -3: -2 without builtins, -10: dump values (Perl style), -11: dump values (lines), -100: print POD.
=item B<lineend> (scalar)
        undef
line ending to use: (DOS, MAC, UNIX or be explicit if you can, taken from data if undefined, finally resorting to UNIX) (from Text::NumericData)
=item B<numformat>, B<N> (array)
        []
printf formats to use (if there is no "%" present at all, one will be prepended) (from Text::NumericData)
=item B<numregex> (scalar)
        '[\\+\\-]?\\d*\\.?\\d*[eE]?\\+?\\-?\\d*'
regex for matching numbers (from Text::NumericData)
=item B<outsep> (scalar)
        undef
use this separator for output (leave undefined to use input separator, fallback to TAB) (from Text::NumericData)
=item B<quote> (scalar)
        undef
quote titles (from Text::NumericData)
=item B<quotechar> (scalar)
        undef
quote character to use (derived from input or ") (from Text::NumericData)
=item B<separator> (scalar)
        undef
use this separator for input (otherwise deduce from data; TAB is another way to say "tabulator", fallback is    ) (from Text::NumericData)
=item B<stats>, B<s> (scalar)
        0
add columns with statistic values for the bins (1: standard deviation, 2: min and max values, 3: stddev, min, max)
=item B<strict>, B<S> (scalar)
        0
strictly split data lines at configured separator (otherwise more fuzzy logic is involved) (from Text::NumericData)
=item B<text>, B<T> (scalar)
        1
allow text as data (not first column) (from Text::NumericData)
=item B<version> (scalar)
        0
print out the program version
