reStructuredText support (experimental)
|
|
|
|
Example::
|
|
|
|
def configure(conf):
|
|
conf.load('rst')
|
|
if not conf.env.RST2HTML:
|
|
conf.fatal('The program rst2html is required')

def build(bld):
|
|
bld(
|
|

|
|
type = 'rst2html', # rst2html, rst2pdf, ...
|
|
source = 'index.rst', # mandatory, the source
|
|
deps = 'image.png', # to give additional non-trivial dependencies
|
|
)
|
|
|
|
By default the tool looks for a set of programs in PATH.
|
|
The tools are defined in `rst_progs`.
|
|
To configure with a special program use::
|
|
|
|
$ RST2HTML=/path/to/rst2html waf configure
|
|
|
|
This tool is experimental; don't hesitate to contribute to it.
