CA storage for cURL on Mavericks I was troubleshooting a problem with Arcanist and Phabricator on MacOSX, a cURL/60 error, but it wasn't clear how to check where the php curl libraries were getting their Certificate Authority trust from.  

Where or how does Mavericks handle trust storage for Certificate Authorities and self-signed certificates for cURL and/or the curl libraries?  Is there a source of documentation on this which I'm missing?

Nb, I'm pretty new with MacOS.
For documentation: If you want to read any of the Unix library instructions, you can open the Terminal application. Type "man curl" and you will get the manual for the curl function. There is an app called "iMan" which does a nice job of showing manual pages in a more readable format, and can search for manuals or show variations of similar libraries (https://sourceforge.net/projects/iman-macosx).
