Ant target for autogenerating changelog based on Git tags
<!--
Ant target for autogenerating a changelog based on Git tags
Workflow:
1. Do all of your checkins for a given version.
2. When you're ready to officially create a new version, tag it using git tag, such as "git tag v0.3.0".
3. If you don't already have a file named CHANGELOG in the root directory, make one.
4. Run "ant changelog.update"

# Output lines suitable for sysctl configuration based

# On Linux, you can use it as follows (as root):

# ./shmsetup >> /etc/sysctl.conf

Slightly tighter CORS config for nginx
#
# Slightly tighter CORS config for nginx

# A modification of https://gist.github.com/1064640/ to include a white-list of URLs
#
# Despite the W3C guidance suggesting that a list of origins can be passed as part of
# Access-Control-Allow-Origin headers, several browsers (well, at least Firefox)
# don't seem to play nicely with this.

The enclosed config.xml file will instruct Jenkins to check out and build llvm + clang, archiving the resulting clang binary.
The configuration will build daily and will retain builds for 5 days.
To add it to your Jenkins install, just copy the config.xml file to e.g.:
jobs/Clang/config.xml
Then "reload configuration" in Jenkins, or stop and start Jenkins to reload it implicitly.
