With this bundle within the kernel tree we have a good starting point to compose reST documents from scratch and to migrate book by book from DocBook to reST. I insist to migrate book by book, because there are some broken books. Broken by that, that some sources have changed but not the corresponding documentation which use the comments of these sources ... grap "Ooops" in the builded (xml or rst) docs. E.g. I greped the .rst file and found the following Oops in the migrated books: ./books/mtdnand/pubfunctions-000-012.rst:13:Oops ./books/scsi/mid_layer-000-001-016-003.rst:13:Oops ./books/s390-drivers/ccw-000-004-003.rst:13:Oops ./books/device-drivers/devdrivers-000-003-048.rst:13:Oops ./books/device-drivers/devdrivers-000-003-050.rst:13:Oops ./books/device-drivers/Basics-000-001-002.rst:13:Oops ./books/device-drivers/devdrivers-000-003-031.rst:13:Oops ./books/device-drivers/Basics-000-009-032.rst:13:Oops ./books/kernel-api/kernel-lib-000-004-008.rst:13:Oops ./books/gadget/api-000-011-005.rst:13:Oops ./books/gadget/api-000-011-009.rst:13:Oops ./books/gadget/api-000-011-007.rst:13:Oops ./books/gadget/api-000-011-003.rst:13:Oops ./books/gadget/api-000-011-011.rst:13:Oops ./books/genericirq/intfunctions-000-009.rst:13:Oops ----- Summarize ---- @Jonathan: what do you think? Should I prepare a patch with a basic reST (sphinx) build infrastructure, including * a folder for sphinx docs: ./Documentation/sphinx/ * flat-table & kernel-doc extension at ./Documentation/sphinx/extensions * a patch with rst-Output for the kernel-doc perl script at ./scripts/kernel-doc * An example document "HowTo document with reST" at ./Documentation/sphinx/kernel-doc-rst-howto which at minimum describes the "flat-table" and "kernel-doc" directive and the requirements for a building docs. * a make file which fit into the kernel Makefile infrastructure (not the one created by sphinx-quickstart). -- Markus ---- To unsubscribe from this list: send the line "unsubscribe linux-doc" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
