+File uses magic numbers to determine a file type. These magic numbers come with
+File in a plain text file.  File internally compiles this database each time it
+is run. This is not the normal type of operation for File since compiling a
+plain text file each time is not the fastest way to do it. File offers an
+option "-C" to compile this magic number file. The reason this isn't done
+automagically is that some people like to work on the magic numbers.  On the
+other hand many people didn't get it that they should compile the magic
+numbers, so the author of File added a warning when the plain text magic file
+is used. As we usually won't work on the plain text magic file, we 
+compile this file, because it's faster, fixes that annoying warning and is how
+it was meant to be:
