# The <code>number_pages</code> method is a simple way to number the pages of
# your document. It should be called towards the end of the document since
# pages created after the call won't be numbered.
#
# It accepts a string and a hash of options:
#
# <code>start_count_at</code> is the value from which to start numbering pages
#
# <code>total_pages</code> If provided, will replace <code>total</code> with
# the value given. Useful for overriding the total number of pages when using
# the start_count_at option.
#
# <code>page_filter</code>, which is one of: <code>:all</code>,
# <code>:odd</code>, <code>:even</code>, an array, a range, or a Proc that
# receives the page number as an argument and should return true if the page
# number should be printed on that page.
#
# <code>color</code> which accepts the same values as <code>fill_color</code>
#
# As well as any option accepted by <code>text_box</code>
#
