# This program illustrates the basic use of the SimpleMarkup
|
|
# class. It extracts the first comment block from the
|
|
# simple_markup.rb file and converts it into HTML on
|
|
# standard output. Run it using
|
|
#
|
|
# % ruby sample.rb
|
|
#
|
|
# You should be in the sample/rdoc/markup/ directory when you do this,
|
|
# as it hardwires the path to the files it needs to require.
|
|
# This isn't necessary in the code you write once you've
|
|
# installed the package.
|
|
#
|
|
# For a better way of formatting code comment blocks (and more)
|
|
# see the rdoc package.
