# Synopsis:
#
#      pageNumberLookup.rb filename.html > outputFile.html
#
# This script is used to replace symbolic references to locations in the OpenCL
# specification with page number references. This can be used when you want the
# reference page to refer to section XYZ of the OpenCL spec with a link and have
# the link open the spec document to section XYZ. This approach is based on the
# "named destination" feature for PDF files.
#
# Ideally we wanted to link to the named destinations, but inconsistencies between
# versions of MS Word and other limitations prevent us from doing that at this time.
# So, this is a second-best solution in which we map symbolic names to page
# numbers, then the link will open the spec to the specified page. To use this
# solution, refer to a section in the spec using a symbolic name that you make up
# in a <olink /> element with a uri attribute that is the symbolic name. Then add
# the keyword to the lookup table below with the corresponding page number from
# the Spec.
#
# For example to link to the spec section for gl_sharing, use:
#
#    <olink uri="gl_sharing">OpenCL Specification</olink>
#
# The xsltproc program generates a temporary HTML file where the XML line above
# is transformed into a line containing a placeholder URL:
#
#    <a href="http://www.khronos.org/registry/cl/specs/opencl-XXX.pdf#namedest=gl_sharing">
#	    OpenCL Specification</a>
#
# When this lookup program is run on the temporary HTML file, it will look up the
# keyword and replace the placeholder text in the HTML file with the final URL.
# The final URL is specified below in Specnames. This transforms the placeholder
# line into the final form, in this manner:
#
#    <a href="http://www.khronos.org/registry/cl/specs/opencl-2.0.pdf#page=279">
#	    OpenCL Specification</a>
#
# (You can control what the first part of the URL is by modifying the SpecBaseUrl
# variable in the opencl-man.xsl file.)


# Here are the real spec filenames of the OpenCL 2.0 spec documents (see comments above):
