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:

DIAGNOSTICS

       There aren't many at this time.

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.
