This is an automated email from the git hooks/post-receive script. It was generated because a ref change was pushed to the repository containing the project "OCT: A portable Lisp implementation for quad-double precision floats".

The branch, master has been updated via de65a54b545af76b6df16f3de36e54763ce97235 (commit) via fb7212315ca5f592ef768c2636e7b3cd745473e4 (commit) via 581a0a08f04a985424c09b6a7b3661d2eb58c3e9 (commit) via 76ea9b133d74861db511d7c3e3a29653ce4ebda7 (commit) via 25129063aaa6168763b447db6f033359a19b60e0 (commit) via 22db89aa72af64360ed2d0f97709fc26ca01368b (commit) via fd281d5fcf9fcddb459b4fb12e6922ff2a2121a8 (commit) from e6a3f286122ea99d65a6448c3c41d0bdc411b2d7 (commit)
