NAME

       codechanges - computes the amount of code changes between two code trees or single files

SYNOPSIS

       codechanges [-n] old-directory new-directory

       codechanges [-n] old-file new-file

DESCRIPTION

       codechanges  recursively  compares  the  two  named  directories  (or  files)  calculating
       new/deleted/changed lines, not including comments or blank lines, in files which appear to
       be  source files (C, C++, shell, and Makefiles).  To include comments and blank lines, use
       the -n option.

APPLICATIONS

       codechanges is purpose designed to measure the amount of code change between milestones in
       a  project's  life.   The  following  output is from two stages, plus some artificial test
       cases, in the pmccabe code stream:

BUGS

       codechanges thinks it knows what source files are interesting and the user may  not  agree
       with  its  choices.   It's  a script and should be easy to modify.  Ultimately this should
       probably be configurable.

       codechanges uses a program called decomment which guesses how to de-comment a  file  based
       on its file name and it's not always perfect.
