BlOut 2.6

Blout removes extra blank lines from a file, collapsing multiple blank
lines down to one, (or removing them altogether with the -compact option).
It also ensures the file has a final CrLf. It also trims any blank lines
off the beginning and end of the file. It also converts all line endings
to Windows standard CrLf form. It trims trailing tabs and spaces from
each line.

Blout is not that bright. It does not understand wildcards except those
expanded by the OS. You can put multiple files on the command line.

usage:

blout.exe somefile.txt anotherfile.txt

You can also ask it to get rid of blank lines altogether with:

blout.exe -compact somefile.txt anotherfile.txt

For Windows, C source included.

It can handle arbitrarily large files. They do not have to fit in RAM.
Because of this feature, files will get a new date whether anything
changed or not. It is designed to that if you abort part way through,
your original file will be unchanged.
