pxz - Parallel LZMA compressor compatible with XZ.

SYNOPSIS

-h, --help
Display help.
-f, --force
Force operation.
-c, --stdout
Write results to standard output.
-k, --keep
Write results to standard output.
-T, --threads
Maximal number of threads to run simultaneously.
-D, --context-size
Context size per one thread specified as a multiple of dictionary size for active compression level.
-V, --version
Display version of PXZ.

EXAMPLES

pxz file1 file2
Compress file1 and file2 to file1.xz and file2.xz using default settings.
pxz -T4 file1
Compress file1 with default compression and maximum of 4 threads.
pxz -k -9 file1
Use maximal compression and keep the original file1, use default number of threads.
pxz -f -T4 file1
Compress file with default compression and with 4 threads.
pxz -kvf -3 -T8 file1
Use -3 compression, keep the original file, use 8 threads and show progress.
tar Oc dir1 | pxz -D 12 -cv - > dir1.tar.xz
Move dir1 into tar, then compress it with the context of 12 sizes of dictionary per thread, show progress and write result to dir1.tar.xz.

"Breadth. Circle. Desert. Monarch. Month. Wisdom. (for which there are
No rhymes)" was just the title, and I only read that far.

That was because I felt like some old agent-of-the-Czar
When a plotter swims within the scope of his exertions,
And I was scared this hothead would start hedging his assertions
Before I had him dead-to-rights. (A Chekan's or a SMERSHian's
Lot, you know, is not a happy one.) He might retract.

A liar is a liar is a liar. That's his act.
But six distinct demonstrable defiances-of-fact
Before he hits line one? That's taking aim at the World's Record.
I wanted this quark-colored tangerine-flake double-deckered
Omnibus of absurdities to make it to the checkered
Flag. He started fast, but could he forge on? Was he s e r i o u s?

He had the Grand Prix style all right. Intense. Composed. Imperious.
And lies to burn. Poor lies, in no wise deep or deleterious.
He drove them home like thumb (or rather tooth nail fist and chin) tacks.
He planted Cosmic Glints to make you whimper for a glint-axe.
"Unconstellated words rain down...inexorable syntax"
Etcetera Etcetera.

It's not that I'd set up,
Like Carrie Nation beating back the drunkard from his cup,
To scourge the world of liars. I'd as soon be Offissa Pup.
I'd sooner hassle fetishists and call myself a bra-narc.

If I were Lord of All (or even constitutional monarch)
I'd send a Deluge down, with one-way tickets on the Non-ark
For lying priests and pedagogues. They make a feller's fez hurt.
But whom does Keats's whopper about corpulent Cortez hurt?
Or any poet's whopper? If he wants to say the Desert
Is made of pea-green camambert, hell, welcome to the circle.

We listen to a Bard the way a certain kind of jerk'll
Listen to the leaves or listen to a percolator perkle.
As long as he can grind em out, a dozen-or-so a month,
We'll praise him to the nth degree, and to the n-plus-1th.
He could have called the thing "Fifth. Sixth. Eighth. Ninth. Twelfth.
Baker's dozenth"
For all we care. We'll cheer him to the w-x-y-zedth
As long as his flimflammeries have brio and have breadth
And don't come on like nursery-nannies pushing early to bedth
To three-year-olds with jingles about Health and Wealth and Wisdom.

He should look out though. He might take himself in, and that is dumb.

Do that, and sure as malheur is the better part of Msdom,
Sententiousness will sidle in with snapshots in his wallet
To lay a little something on us camels: some small strawlet
Of Wisdom, say, or Beauty. Take this poem now. I call it
"Width. Rhombus. (see Lozenge.) Glacier. Despot. Fortnight. Bilge."
I t o l d myself: "No overkill. Go easy on the bilge."
But then. T u e u r is human. And what rhymes with bilge is bilge.
