# PSEUDO CODE
# -----------
# summarize the treatment done by this module using the usual control structures
# provided by Python, but normal text or sentences instead of variables
# names or function calls.


# ------------
# DEPENDENCIES
# ------------
# sys is the most-used module which contains a set of system-level components.
# os provides functions like os.path.join() and os.environ[var] for interacting with the OS.
# glob.glob() finds all the pathnames matching a specified pattern according to the shell rules.
# re provides regular expression tools re.sub() and re.search() for advanced string processing.
# the Sybase module provides function like sybase.connect() to connect to sybase DB.
# time offers functionality like mktime() and strptime() for manipulating time.
# string offers functionality like lstrip(), rstrip(), replace() ...
# socket uses functions like gethostname().
