mk_check_docbook — Check for DocBook prerequisites on the build system
mk_check_docbook
Checks for the availability of DocBook XSL stylesheets
and a usable XSLT processor (currently only xsltproc).
The result can be tested with mk_have_docbook.
If successful, you may then use functions such as
mk_docbook_html to generate documentation
from DocBook sources as part of your project.
