\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.
