PSI3 is an ab-initio quantum chemistry program.  It is especially designed to
accurately compute properties of small to medium molecules using highly
correlated techniques.
It can compute energies and gradients for the following methods:
* Closed shell and general restricted open shell Hartree-Fock (RHF/ROHF)
(including analytical hessians for RHF)
* Closed shell Moeller-Plesset pertubation theory (MP2)
* Complete active space SCF (CASSCF)
* Coupled-cluster singles doubles (CCSD)
* Coupled-cluster singles doubles with pertubative triples (CCSD(T))
(only for unrestricted (UHF) reference wavefunctions)
Additionally, it can compute energies for the following methods:
* Unrestricted open shell Hartree-Fock (UHF)
* Closed/open shell Moeller-Plesset pertubation theory (MP2)
* Closed shell explicitly correlated MP2 theory (MP2-R12) and spin-component
scaled MP2 theory (SCS-MP2)
* Multireference configuration-interaction (MRCI)
* Coupled-cluster singles doubles with pertubative triples (CCSD(T))
* Second/third-order approximate coupled-cluster singles doubles (CC2/CC3)
* Multireference coupled-cluster singles doubles (MRCCSD)
* Closed shell and general restricted open shell equation-of-motion coupled-
cluster singles doubles (EOM-CCSD)
Further features include:
* Flexible, modular and customizable input format
* Excited state calculations with the CC2/CC3, EOM-CCSD, CASSCF, MRCI and
MRCCSD methods
* Internal coordinate geometry optimizer
* Harmonic frequencies calculations
* One-electron properties like dipole/quadrupole moments, natural orbitals,
electrostatic potential, hyperfine coupling constants or spin density
* Utilization of molecular point-group symmetry to increase efficiency

[ Michael Banck ]
* debian/patches/11_testsuite.patch: New patch, adds CCSD(T)/CASSCF
geometry optimizations with analytical gradients and CC2/EOM-CCSD/MRCC
energies to quicktests.  Further, do not exit immediately if one test
* debian/patches/12_613088_fix_manpage.patch: New patch, removes the
mangling of the main psi3 manpage with macros (closes: #613088).
* debian/upstream: Removed WIREs article for now as it is specfic to PSI4.
* debian/rules (override_dh_auto_test): Only run testsuite if
DEB_BUILD_OPTIONS does not contain `nocheck', as per policy.
* debian/psirc.example: New file, contains an example ~/.psirc.
* debian/rules (override_dh_auto_install): Install it.
[ Daniel Leidert ]
* debian/compat: Increased level to 7.
* debian/control (Uploaders): Removed myself.
(Standards-Version): Bumped to 3.9.4.
(Build-Depends): Added required version for autotools-dev addon. Replaced
bison by byacc (closes: #713570).
(Vcs-Browser, Vcs-Svn): Fixed vcs-field-not-canonical.
(DM-Upload-Allowed): Dropped.
* debian/dirs: Renamed to debian/psi3.dirs.
* debian/docs: Renamed to debian/ Added user manual.
* debian/psi3.doc-base: Added.
* debian/rules: Use variables instead of commands (e.g. MAKE, RM). Call
the autotools_dev addon.
(override_dh_auto_test): Removed the nofilter check. dh will do this.
* debian/upstream: Added.
* debian/README.source: Dropped obsolete file.
* debian/TODO: Dropped.
* debian/patches/*.patch: Added header tags.
* debian/patches/13_parallel-make.patch: Added.
- Try to improve the compilation process of flex/byacc related stuff.
* debian/patches/14_fix_typos.patch: Added.
- Fix spelling errors.
* debian/patches/series: Adjusted.
