Fix public issue 82: Stop distributing benchmark data files that have
unclear or unsuitable licensing. In general, we replace the files we can with liberally licensed data, and remove all the others (in particular all the parts of the Canterbury corpus that are not clearly in the public domain). The replacements do not always have the exact same characteristics as the original ones, but they are more than good enough to be useful for benchmarking. git-svn-id: https://snappy.googlecode.com/svn/trunk@83 03e5f5b5-db94-4691-08a0-1a8bf15f6143

-.TH XARGS 1L \" -*- nroff -*-
-.SH NAME
-xargs \- build and execute command lines from standard input
-.SH SYNOPSIS
-.B xargs
-[\-0prtx] [\-e[eof-str]] [\-i[replace-str]] [\-l[max-lines]]
-[\-n max-args] [\-s max-chars] [\-P max-procs] [\-\-null] [\-\-eof[=eof-str]]
-[\-\-replace[=replace-str]] [\-\-max-lines[=max-lines]] [\-\-interactive]
-[\-\-max-chars=max-chars] [\-\-verbose] [\-\-exit] [\-\-max-procs=max-procs]
-[\-\-max-args=max-args] [\-\-no-run-if-empty] [\-\-version] [\-\-help]
-[command [initial-arguments]]
-.SH DESCRIPTION
-This manual page
-documents the GNU version of
-.BR xargs .
-.B xargs
-reads arguments from the standard input, delimited by blanks (which can be
-protected with double or single quotes or a backslash) or newlines,
-and executes the
-.I command
-(default is /bin/echo) one or more times with any
-.I initial-arguments
-followed by arguments read from standard input. Blank lines on the
-standard input are ignored.
-.P
-.B xargs
-exits with the following status:
-.nf
-0 if it succeeds
-123 if any invocation of the command exited with status 1-125
-124 if the command exited with status 255
-125 if the command is killed by a signal
-126 if the command cannot be run
-127 if the command is not found
-1 if some other error occurred.
-.fi
-.SS OPTIONS
-.TP
-.I "\-\-null, \-0"
-Input filenames are terminated by a null character instead of by
-whitespace, and the quotes and backslash are not special (every
-character is taken literally). Disables the end of file string, which
-is treated like any other argument. Useful when arguments might
-contain white space, quote marks, or backslashes. The GNU find
-\-print0 option produces input suitable for this mode.
-.TP
-.I "\-\-eof[=eof-str], \-e[eof-str]"
-Set the end of file string to \fIeof-str\fR. If the end of file
-string occurs as a line of input, the rest of the input is ignored.
-If \fIeof-str\fR is omitted, there is no end of file string. If this
-option is not given, the end of file string defaults to "_".
-.TP
-.I "\-\-help"
-Print a summary of the options to
-.B xargs
-and exit.
-.TP
-.I "\-\-replace[=replace-str], \-i[replace-str]"
-Replace occurences of \fIreplace-str\fR in the initial arguments with
-names read from standard input.
-Also, unquoted blanks do not terminate arguments.
-If \fIreplace-str\fR is omitted, it
-defaults to "{}" (like for `find \-exec'). Implies \fI\-x\fP and
-\fI\-l 1\fP.
-.TP
-.I "\-\-max-lines[=max-lines], -l[max-lines]"
-Use at most \fImax-lines\fR nonblank input lines per command line;
-\fImax-lines\fR defaults to 1 if omitted. Trailing blanks cause an
-input line to be logically continued on the next input line. Implies
-\fI\-x\fR.
-.TP
-.I "\-\-max-args=max-args, \-n max-args"
-Use at most \fImax-args\fR arguments per command line. Fewer than
-\fImax-args\fR arguments will be used if the size (see the \-s option)
-is exceeded, unless the \-x option is given, in which case \fBxargs\fR
-will exit.
-.TP
-.I "\-\-interactive, \-p"
-Prompt the user about whether to run each command line and read a line
-from the terminal. Only run the command line if the response starts
-with `y' or `Y'. Implies \fI\-t\fR.
-.TP
-.I "\-\-no-run-if-empty, \-r"
-If the standard input does not contain any nonblanks, do not run the
-command. Normally, the command is run once even if there is no input.
-.TP
-.I "\-\-max-chars=max-chars, \-s max-chars"
-Use at most \fImax-chars\fR characters per command line, including the
-command and initial arguments and the terminating nulls at the ends of
-the argument strings. The default is as large as possible, up to 20k
-characters.
-.TP
-.I "\-\-verbose, \-t"
-Print the command line on the standard error output before executing
-it.
-.TP
-.I "\-\-version"
-Print the version number of
-.B xargs
-and exit.
-.TP
-.I "\-\-exit, \-x"
-Exit if the size (see the \fI\-s\fR option) is exceeded.
-.TP
-.I "\-\-max-procs=max-procs, \-P max-procs"
-Run up to \fImax-procs\fR processes at a time; the default is 1. If
-\fImax-procs\fR is 0, \fBxargs\fR will run as many processes as
-possible at a time. Use the \fI\-n\fR option with \fI\-P\fR;
-otherwise chances are that only one exec will be done.
