open (OUT, ">$outfile") or die "Couldn't open output file: $!";

while (my $sLine = <IN>) {
next if $sLine =~ m/^s*$/;  #remove empty lines. Without this, still destroys empty lines except for the first one.
$sLine=~s/^s+//;            #strip leading/trailing whitespace
$sLine=~s/s+$//;
print OUT qq{$sLine
} unless ($hTmp{$sLine}++);
