Loads tables from text files in various formats.  The base name of the
text file must be the name of the table that should be used.
If one uses sockets to connect to the MySQL server, the server will open and
read the text file directly. In other cases the client will open the text
file. The SQL command 'LOAD DATA INFILE' is used to import the rows.

Usage: mysqlimport [OPTIONS] database textfile...
