Does trailing white-space annoy you?
StripEnd removes all trailing white-spaces in a text file.
I use it to reduce the size of my web pages. Trailing white-space serves no purpose
and in the case of a web page, makes it longer to download.
I also use it on the code I write. Besides that fact that trailing white-space in code
is a pet-peeve of mine, it also reduces the compile time because there's less to parse.
For a large program that gets compiled a lot, this could add up to some significant time savings.
