Hello,
Splitting a sentence using the full-stop/question-mark/exclamation is a common device. Whereas the question-mark / exclamation do not pose too much of a problem; the full-stop as a sentence delimiter raises certain issues because of its varied use:
just to name a few.

Hello,
Currently we have a Oracle X4100 ( Solaris 10 ) server with disk failure. Originally our hardware team thought the disk can be hot-swap, when they stood in front of the server, none of the disk failure LED were on, so now we have no idea which disk is the bad one for replacement.

ppmtopgm - convert a portable pixmap into a portable graymap
SYNOPSIS
ppmtopgm [ppmfile]
DESCRIPTION
Reads a portable pixmap as input. Produces a portable graymap as output. The output is a "black and white" rendering of the original
image, as in a black and white photograph. The quantization formula used is .299 r + .587 g + .114 b.
Note that although there is a pgmtoppm program, it is not necessary for simple conversions from pgm to ppm , because any ppm program can
read pgm (and pbm ) files automatically. pgmtoppm is for colorizing a pgm file. Also, see ppmtorgb3 for a different way of converting
color to gray. And ppmdist generates a grayscale image from a color image, but in a way that makes it easy to differentiate the original
colors, not necessarily a way that looks like a black and white photograph.
QUOTE
Cold-hearted orb that rules the night
Removes the colors from our sight
Red is gray, and yellow white
But we decide which is right
And which is a quantization error.
