Treewatch watches a directory for a specified type
of file to change. When one of the files changes,
treewatch runs a program of the user's choice. By
default, treewatch will watch the current
directory and run "make" when changes are detected
in files ending in .cpp, .c, or .h. The user can
specify any number of directories to watch, any
number of file types to watch for, and any command
line to run.
