Merging Lines based on criteria
Hello,

Need help with following scenario.

A file contains following text:

Code:
{beginning of file}
New: This is a new record and it is not
on same line. Since I have lost touch with script
take this challenge and bring all this in one line.
New: Hello losttouch. You seem to be struggling with 
this really simple challenge.
New: It is better that I ask some expert on unix.com
They will show you this is simple enough.
{end of file}

What I am trying to accomplish is to get all the lines starting from "New:" until next "New:" is read; on to one line. Resultant lines should be like:

New: This is a new record and it is not on same line. Since I have lost touch with script take this challenge and bring all this in one line.
New: Hello losttouch. You seem to be struggling with this really simple challenge.
New: It is better that I ask some expert on unix.com.They will show you this is simple enough.

As I mentioned in the above statements, I have lost touch with this, I am really struggling to accomplish this task. Any help is greatly appreciated.

Thanks so much.

EDIT: Needless to say that if I read next "New:" (lets say in any variable) it implies, my previous record is complete and should be displayed or appended to a file.

EMPTY-PAGE(1)							 ExactImage Manual						     EMPTY-PAGE(1)

NAME

       empty-page - empty page detector of the ExactImage toolkit

SYNOPSIS

       empty-page [option...] {-i | --input} input-file

       empty-page {-h | --help}

DESCRIPTION

       ExactImage is a fast C++ image processing library. Unlike many other library frameworks it allows operation in several color spaces and bit
       depths natively, resulting in low memory and computational requirements.

       empty-page counts dark pixels of a black and white image and decides with a threshold whether the page is most probably empty, and thus can
       be removed from the image processing stream.

OPTIONS

       -i file, --input file
	   Read image from the specified file.

       -m n, --margin n
	   Set width of border margin to skip. For speed reasons, the margin has to be a multiple of 8. The default is 16.

       -p x, --percentage x
	   Set fraction of permissible dark pixels. The default is 0.05 (5%).

       -h, --help
	   Display help text and exit.

EXAMPLES

	   $ empty-page -i test.tif
	   The image has 75461 dark pixels from a total of 1060992 (7.11231%).
	   non-empty

EXIT STATUS

       The exit status is 0 if the image is mostly white, 1 otherwise.
