The `netrc' class parses and encapsulates the netrc file format used by
the UNIX `ftp' program and other FTP clients.
`netrc([file])'
A `netrc' instance or subclass instance encapsulates data from a
netrc file. The initialization argument, if present, specifies the
file to parse. If no argument is given, the file `.netrc' in the
user's home directory will be read. Parse errors will raise
`NetrcParseError' with diagnostic information including the file
name, line number, and terminating token.
`NetrcParseError'
Exception raised by the `netrc' class when syntactical errors are
encountered in source text. Instances of this exception provide
three interesting attributes: `msg' is a textual explanation of
the error, `filename' is the name of the source file, and `lineno'
gives the line number on which the error was found.
