Class LineStripper

      org.apache.tools.ant.Task
          org.activemath.util.LineStripper

public class LineStripper
extends org.apache.tools.ant.Task

A simple utility to strip the lines containing a substring. The attributes are:

• source: the source file
• destination: the destination file
• lineContent: the string to strip
• encoding: (optional) the encoding to be used for both reading and writing, defaults to the platform encoding)
• force: (optional) forces the conversion ignoring modification dates (defaults to false, that is replacement will not occur in case the destination, if it exists, is newer than the source)
• atLineStart: wether the string is to be found at line start, defaults to false, (note that spaces are part of this)

The input is read using any line-ending mechanism (as provided by java's java.io.LineNumberReader) and output using the system-dependent line-ending mechanism.
