perror, Explaining Error Codes
------------------------------
`perror' can be used to print error message(s). `perror' can be invoked
like this:
shell> perror [OPTIONS] [ERRORCODE [ERRORCODE...]]
For example:
shell> perror 64 79
Error code 64: Machine is not on the network
Error code 79: Can not access a needed shared library
`perror' can be used to display a description for a system error code,
or an MyISAM/ISAM table handler error code. The error messages are
mostly system dependent.
