-Blender Buildbot
-================
-
-Code signing
------------
-
-Code signing is done as part of INSTALL target, which makes it possible to sign
-files which are aimed into a bundle and coming from a non-signed source (such as
-libraries SVN).
-
-This is achieved by specifying `slave_codesign.cmake` as a post-install script
-run by CMake. This CMake script simply involves an utility script written in
-Python which takes care of an actual signing.
-
-### Configuration
-
-Client configuration doesn't need anything special, other than variable
-`SHARED_STORAGE_DIR` pointing to a location which is watched by a server.
-This is done in `config_builder.py` file and is stored in Git (which makes it
-possible to have almost zero-configuration buildbot machines).
-
-Server configuration requires copying `config_server_template.py` under the
-name of `config_server.py` and tweaking values, which are platform-specific.
-
-#### Windows configuration
-
-There are two things which are needed on Windows in order to have code signing
-to work:
-
- `TIMESTAMP_AUTHORITY_URL` which is most likely set http://timestamp.digicert.com
- `CERTIFICATE_FILEPATH` which is a full file path to a PKCS #12 key (.pfx).
-
-## Tips
-
-### Self-signed certificate on Windows
-
-It is easiest to test configuration using self-signed certificate.
-
-The certificate manipulation utilities are coming with Windows SDK.
-Unfortunately, they are not added to PATH. Here is an example of how to make
-sure they are easily available:
-
-```
-set PATH=C:\Program Files (x86)\Windows Kits\10\App Certification Kit;%PATH%
-set PATH=C:\Program Files (x86)\Windows Kits\10\bin\10.0.18362.0\x64;%PATH%
-```
-
-Generate CA:
-
-```
-makecert -r -pe -n "CN=Blender Test CA" -ss CA -sr CurrentUser -a sha256 ^
-         -cy authority -sky signature -sv BlenderTestCA.pvk BlenderTestCA.cer
-```
-
-Import the generated CA:
-
-```
-certutil -user -addstore Root BlenderTestCA.cer
-```
-
-Create self-signed certificate and pack it into PKCS #12:
-
-```
-makecert -pe -n "CN=Blender Test SPC" -a sha256 -cy end ^
-         -sky signature ^
-         -ic BlenderTestCA.cer -iv BlenderTestCA.pvk ^
-         -sv BlenderTestSPC.pvk BlenderTestSPC.cer
-
-pvk2pfx -pvk BlenderTestSPC.pvk -spc BlenderTestSPC.cer -pfx BlenderTestSPC.pfx
-```

-# Signing process overview.
-#
-# From buildbot worker side:
-#  - Files which needs to be signed are collected from either a directory to
-#    sign all signable files in there, or by filename of a single file to sign.
-#  - Those files gets packed into an archive and stored in a location location
-#    which is watched by the signing server.
-#  - A marker READY file is created which indicates the archive is ready for
-#    access.
-#  - Wait for the server to provide an archive with signed files.
-#    This is done by watching for the READY file which corresponds to an archive
-#    coming from the signing server.
-#  - Unpack the signed signed files from the archives and replace original ones.
-#
-# From code sign server:
-#  - Watch special location for a READY file which indicates the there is an
-#    archive with files which are to be signed.
-#  - Unpack the archive to a temporary location.
-#  - Run codesign tool and make sure all the files are signed.
-#  - Pack the signed files and store them in a location which is watched by
-#    the buildbot worker.
-#  - Create a READY file which indicates that the archive with signed files is
-#    ready.
