 * PDF파일을 반으로 자르는 방법(without Acrobat)
  * 목적 : [Workshop/2008Spring]에서 이주호님이 Acrobat Professional로 보여준 방법을 최대한 쉽게(?) 프로그램으로 해결해본다.

# watermark.pdf크기가 같아야 한다.
#page4 = input1.getPage(3)
#watermark = PdfFileReader(file("watermark.pdf", "rb"))

# 5페이지의 왼쪽반을 가져온다.

   * 최종소스 document1.pdf문서를 document-output.pdf로 만들어줍니다.
    * 모든 페이지를 반으로 자릅니다.
    * 첫페이지의 오른쪽 반 즉 2page가 실제로는 마지막 페이지가 되어야 합니다.
