+/**
+ * Sample Gitblit Pre-Receive Hook: subgit
+ * http://subgit.com
+ *
+ * The Pre-Receive hook is executed after an incoming push has been parsed,
+ * validated, and objects have been written but BEFORE the refs are updated.
+ * This is the appropriate point to block a push for some reason.
+ *
+ * This script is only executed when pushing to *Gitblit*, not to other Git
+ * tooling you may be using.
+ *
+ * If this script is specified in *groovy.preReceiveScripts* of gitblit.properties
+ * or web.xml then it will be executed by any repository when it receives a
+ * push. If you choose to share your script then you may have to consider
+ * tailoring control-flow based on repository access restrictions.
+ *
+ * Scripts may also be specified per-repository in the repository settings page.
+ * Shared scripts will be excluded from this list of available scripts.
+ *
+ * This script is dynamically reloaded and it is executed within it's own
+ * exception handler so it will not crash another script nor crash Gitblit.
+ *
+ * This script may reject one or more commands, but will never return false.
+ * Subsequent scripts, if any, will always be invoked.
+ *
+ * Bound Variables:
+ * gitblit Gitblit Server com.gitblit.GitBlit
+ * repository Gitblit Repository com.gitblit.models.RepositoryModel
+ * receivePack JGit Receive Pack org.eclipse.jgit.transport.ReceivePack
+ * user Gitblit User com.gitblit.models.UserModel
+ * commands JGit commands Collection<org.eclipse.jgit.transport.ReceiveCommand>
+ * url Base url for Gitblit String
+ * logger Logs messages to Gitblit org.slf4j.Logger
+ * clientLogger Logs messages to Git client com.gitblit.utils.ClientLogger
+ *
+ * Accessing Gitblit Custom Fields:
+ * def myCustomField = repository.customFields.myCustomField
+ *
+ *
+ * Usage:
+ *
+ * 1. Create Git repository in GitBlit;
+ * 2. Register subgit pre-receive groovy hook in repository settings;
+ * 3. Install SubGit into created repository:
+ * subgit configure --svn-url <SVN_URL> <GITBLIT_HOME>/data/git/<GIT_REPO>
+ * subgit install <GITBLIT_HOME>/data/git/<GIT_REPO>
+ *
+ * You can enable SubGit pre-receive groovy hook for all repositories: this shouldn't
+ * cause any problems as the hook skips those repositories with no SubGit installed.
