 If you have written a cool CodeQL query that you would like to share with the community, then please open a pull request to add it to the [CodeQL_Queries](CodeQL_Queries) sub-directory. Put your query in its own new sub-directory. For example: `CodeQL_Queries/cpp/mynewsubdir/mycoolquery.ql`. Of course, if you think your query might be eligible for a [bounty](https://securitylab.github.com/bounties), then you should open a pull request to the [codeql](https://github.com/github/codeql) repo instead, as we do not offer bounties for queries submitted to this repo. The queries in this repo are usually highly specialized queries that only make sense for a specific codebase, such as queries that specifically target [Chrome](CodeQL_Queries/cpp/Chrome) or [Apache Struts](CodeQL_Queries/java/Apache_Struts_CVE-2018-11776), or utility queries that help you explore your code without necessarily finding a vulnerability. Such queries are inappropriate for the [codeql](https://github.com/github/codeql) repo, which is for general purpose queries only.

 * Each bullet point should consist of a hyperlinked title and a short description. The short description is optional if the title is already self-explanatory.
 * Please add new bullet points at the bottom of the list. In the future, we may choose some other ordering such as alphabetical but for now it is just a sequential list.
