# scons-doc.py - an SGML preprocessor for capturing SCons output
# and inserting it into examples in our DocBook
# documentation
#
# This script looks for some SGML 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 SGML 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>scons -Q foo</scons_output_command>
# <scons_output_command>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 SGML 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.
