+# This script looks for some XML tags that describe SCons example
+# configurations and commands to execute in those configurations, and
+# uses TestCmd.py to execute the commands and insert the output from
+# those commands into the XML that we output. This way, we can run a
+# script and update all of our example documentation output without
+# a lot of laborious by-hand checking.
+#
+# An "SCons example" looks like this, and essentially describes a set of
+# input files (program source files as well as SConscript files):
+#
+# <scons_example name="ex1">
+# <file name="SConstruct" printme="1">
+# env = Environment()
+# env.Program('foo')
+# </file>
+# <file name="foo.c">
+# int main() { printf("foo.c\n"); }
+# </file>
+# </scons_example>
+#
+# The <file> contents within the <scons_example> tag will get written
+# into a temporary directory whenever example output needs to be
+# generated. By default, the <file> contents are not inserted into text
+# directly, unless you set the "printme" attribute on one or more files,
+# in which case they will get inserted within a <programlisting> tag.
+# This makes it easy to define the example at the appropriate
+# point in the text where you intend to show the SConstruct file.
+#
+# Note that you should usually give the <scons_example> a "name"
+# attribute so that you can refer to the example configuration later to
+# run SCons and generate output.
+#
+# If you just want to show a file's contents without worry about running
+# SCons, there's a shorter <sconstruct> tag:
+#
+# <sconstruct>
+# env = Environment()
+# env.Program('foo')
+# </sconstruct>
+#
+# This is essentially equivalent to <scons_example><file printme="1">,
+# but it's more straightforward.
+#
+# SCons output is generated from the following sort of tag:
+#
+# <scons_output example="ex1" os="posix">
+# <scons_output_command suffix="1">scons -Q foo</scons_output_command>
+# <scons_output_command suffix="2">scons -Q foo</scons_output_command>
+# </scons_output>
+#
+# You tell it which example to use with the "example" attribute, and then
+# give it a list of <scons_output_command> tags to execute. You can also
+# supply an "os" tag, which specifies the type of operating system this
+# example is intended to show; if you omit this, default value is "posix".
+#
+# The generated XML will show the command line (with the appropriate
+# command-line prompt for the operating system), execute the command in
+# a temporary directory with the example files, capture the standard
+# output from SCons, and insert it into the text as appropriate.
+# Error output gets passed through to your error output so you
+# can see if there are any problems executing the command.
