\alias{magic_wand_file}
\title{Use the "magic" file that comes with the package}
\usage{
magic_wand_file(force = FALSE)
}
\arguments{
\item{force}{ensure the lastest copy of the pacakge "magic"
database is used.}
}
\description{
The \code{magic_load()} functon from \code{libmagic} can't take ZIP files
and the \code{magic.mgc} file that ships with the package is too large to
be shipped uncompressed. Using this function as the \code{magic_db}
parameter will copy and uncompress the database to a cache directory and
return the full path to the magic file. Subsequent calls will not have to
perform the decompression unless \code{force} is \code{TRUE} or the
cache directory has been cleared.
