# some venture into standard modules

import os

# print all names exported by the module
print dir(os)

# print the module's online manual
print help(os)
# the above is also available in
# interactive mode in Python terminal

# example of using a function
print 'current dir is:', os.getcwd()

# this prints a list of existing modules
print help('modules')

# referecnce
# http://python.org/doc/2.3.4/tut/node12.html

# in Python terminal, type help() then
# modules
# to get a list
# then a module name to see its doc.

# take a gander of its richness and
# suitability

in perl, i don't think there is one way to
list available modules.

one can write a program to find out. Start by
use Data::Dumper; print Dumper \@INC;
to see where is the standard modules located,
then search for *.pm files to get an idea.

because html conversion often breaks the code.
