Appending text to multiple files?

I have a directory of C files(BIG Directory) I want to append (or add) a header (my name...etc)  at the beginning of each file in the directory. The header is big so I put it in a file TEXT. I don't want to go through each file and copy/paste the header. So what script can I use?

# This script appends a header file ($FILE) to

# There might be lots of output from the echo commands
# it is safe to comment them out or erase them.

# PS: If you're going to be doing stuff in UNIX

# Its pretty easy too.

for i in `ls $DIR`
do
echo moving $i to $i.tmp
mv $DIR/$i $DIR/$i.tmp
echo copying $FILE to $i
cp $FILE $DIR/$i
echo appending $i.tmp to $i
cat $DIR/$i.tmp >> $DIR/$i
echo removing $i.tmp
rm $DIR/$i.tmp
