Copy a text file and display it as it is

I have a log file from an analysis software which is in ".txt" form. Data is arranged in some useful order with symbols, matrices etc. in the file. I want to make the contents of it an appendix to my report. Is it possible to copy the entire text file after a short intro, say like this?

\chapter{Appendix}\label{chapter:Appendix}\section{Appendix 1 : Sample log file - XXX Analysis}\label{xxx}

.......................... Here the file contents appear..........................
