This directory contains the source of the SIP website, including all pending/finished/rejected SIPs and SLIPs.
To reject a SIP simply:
git mv pending/_posts/{sip-file} rejected/_posts/{sip-file}
To mark a SIP completed simply:
git mv pending/_posts/{sip-file} completed/_posts/{sip-file}
The process is the same for SLIPs, which are identical except for their layout being slip instead of sip in the document header.
