As a script:
#!perl -w
$/ = ''; # see perldoc perlvar
while (<>) {
        s/ *\n */ /g; # convert newlines to spaces
        s/^ +//; # strip leading spaces
        s/ +$//; # strip trailing spaces
        print $_, "\n";
}


As an oneliner:

perl -ni.bak -e "BEGIN{$/=''}; s/ *\n */ /g; s/^ +//; s/ +$//;print 
$_, qq{\n}" filename.txt

There is a reason for living. There must be. I've seen it somewhere.
It's just that in the mess on my table ... and in my brain
I can't find it.
