Utility classes for IO support.

See: Description

- Interface Summary
  Interface | Description
  --- | ---
  CopyStreamListener | Accepts `CopyStreamEvent`s to track the progress of a stream copying operation.

- Class Summary
  Class | Description
  --- | ---
  CopyStreamAdapter | The CopyStreamAdapter will relay CopyStreamEvents to a list of listeners when either of its bytesTransferred() methods are called.
  CopyStreamEvent | A CopyStreamEvent is triggered after every write performed by a stream copying operation.
  CRLFLineReader | CRLFLineReader implements a readLine() method that requires exactly CRLF to terminate an input line.
  DotTerminatedMessageReader | DotTerminatedMessageReader is a class used to read messages from a server that are terminated by a single dot followed by a <CR><LF> sequence and with double dots appearing at the beginning of lines which do not signal end of message yet start with a dot.
  DotTerminatedMessageWriter | DotTerminatedMessageWriter is a class used to write messages to a server that are terminated by a single dot followed by a <CR><LF> sequence and with double dots appearing at the beginning of lines which do not signal end of message yet start with a dot.
  FromNetASCIIInputStream | This class wraps an input stream, replacing all occurrences of <CR><LF> (carriage return followed by a linefeed), which is the NETASCII standard for representing a newline, with the local line separator representation.
  FromNetASCIIOutputStream | This class wraps an output stream, replacing all occurrences of <CR><LF> (carriage return followed by a linefeed), which is the NETASCII standard for representing a newline, with the local line separator representation.
  SocketInputStream | This class wraps an input stream, storing a reference to its originating socket.
  SocketOutputStream | This class wraps an output stream, storing a reference to its originating socket.
  ToNetASCIIInputStream | This class wraps an input stream, replacing all singly occurring <LF> (linefeed) characters with <CR><LF> (carriage return followed by linefeed), which is the NETASCII standard for representing a newline.
  ToNetASCIIOutputStream | This class wraps an output stream, replacing all singly occurring <LF> (linefeed) characters with <CR><LF> (carriage return followed by linefeed), which is the NETASCII standard for representing a newline.
  Util | The Util class cannot be instantiated and stores short static convenience methods that are often quite useful.

- Exception Summary
  Exception | Description
  --- | ---
  CopyStreamException | The CopyStreamException class is thrown by the org.apache.commons.io.Util copyStream() methods.
