Make the second example command more closely match the demo output, and as
a side effect more clearly show the change in command lines between the
first and second example invocations.

Fix some warns - mainly signedness and unused variables.

Free old arrays if we increase them.

Make ministat(1) vastly faster on huge datasets.

Fix apparent typo. The permitted confidence values include 95%, not 85%.

WARNS fixes: remove two unused variables and add some constness.

Pull ministat into the installed system and write it a man-page.

Improve input parsing:

Add "-C <column>" and "-d <delims>" options to chop up input lines.

Make '#' a comment character, rest of line is ignored.

Avoid coredumps if stddev cannot be computed (if all datapoints are identical)
Small cleanup of label printing.

Fix the way in which median is calculated. If the data source has even
number of data points, value should be calculated by adding two middle
elements and dividing them by 2.

Add option -w to specify graph width.
Use COLUMNS, terminal width for default graph width.

In 2003, a -s flag was added to ministat to separate the
avg/median/stddev bars onto separate lines for readability if the
ranges overlapped. In 2005, ministat was extended to support more than
2 datasets, but the -s code was not updated. It will coredump if run
with -s and >2 sets.

dd a '-n' option to ministat, which causes it to display only summary
statistics, not graph and statistical test output. Useful for automated
processing.

Add support for more than two datasets. Currently limited to 7 though
the limit is only the number of meaningful graph symbols available.

Statistical comparison is performed between the first dataset and
any further datasets.

No objection by: phk

Start the dreaded NOFOO -> NO_FOO conversion.

OK'ed by: core

For variables that are only checked with defined(), don't provide
any fake value.

Added missing DPADD.

Attached is a small patch to ministat that separates the
avg/median/stddev bars onto two lines. Useful for datasets that
overlap.

In case of zero span data supress the histogram plot.

A small statistics tool for gauging the statistical significance
of data from benchmarks etc. Implements "Student's t" for various
confidence levels, defaults to 95%.

If your benchmarks are not significant at the 95% confidence level,
we don't want to hear about it.
