[ILUG] Recursively Remove Comments

[Kevin Lyda]

I think you'll need multi-line reg-ex parsing I suspect.  But if those
are the specific comments you want removed and they all look like
this, then you might get away with:

find . -type f -name '*.php' -execdir sed -i -e '/\*\/\*/,/\*\/\*/d' '{}' '+'

If you're on OS X with a broken sed, add a "" arg in between the -i
and -e.  If you want to append .orig as a backup of the original file,
append .orig to -i on sane unix systems or insert a .orig argument
between the -i and -e on OS X systems.

Doing a "while read file; do blah; done" idiom is generally a bad idea
as newlines and spaces wreck havoc on your script.  In this case there
are also less fork()s.
