Convert Rows to Space Delimited Line

Hello,
I would like to convert a list of rows to a space separated line. Any ideas?

Input file:

"Administration Tools"
"Design Suite"
"Dial-up Networking Support"
"Editors"

desired output

"Administration Tools" "Design Suite" "Dial-up Networking Support" "Editors" 

Thanks,
jaysunn

cat file | tr "\n" " "

Sweet thanks.
I was messing around with paste and others.

[solved]

paste is a good idea too:

paste -sd" " file

awk '$1=$1' ORS=FS  file
