Update: REMOVED DMFT_IPT library. Each code contains IPT codes where necessary.
Small update to check_convergence routines.
Small Update: remove man directory, being too old.
UPDATE: changed names to *.mk files included in the makefiles, now renamed sfmake.inc.
Removed libdmft.mk and DMFT_LIB directory.
update version of splot_*, sread_*. Next commitment: separate data_IO from splot_IO.
TEST the OOgnuplot interface and update splot with that. The idea is to arrive at the
following situation: using splot will plot data to a file + a gnuplot script to plot them, so you can separately plot them yourself
UPDATE: changes in etc/library.conf
Small Update of sfmake and scifor_version.inc
UPDATE: found and solved a bug in FFTGF_FFTW3, routines swapped backward and forward
meaning, so results were -F^* of the correct one (affecting only the real-part).
And a wrong minus sign on exit of fftgf_tau2iw.
Fixed by correcting the sign and restoring correct meaning of forward and backward
transformation in the atomic routines.
UPDATE: removed scifor_version.inc
BIG UPDATE: updated structure of the code. Renamed many files. Removed useless or unused routines.
new entries:
-FFTGF_FFTPACK.f90 is a new FFT module interface based on fftpack routines (f77). Tests are positive, but I DID NOT TESTED IT THOROUGHLY. This can be considered as a backup solution in systems where nor MKL nor FFTW3 are available.
-FUNCTIONS.f90 is a module collecting all the functions routines used in TOOLS, to prevent it becoming a single huge/unreadable file.
-ZEROS.f90 container for zero of functions finder. now brent and broyden are available.
-tools_convergence is a directory containing the many files used in TOOLS to check convergence.

update local .gitignore (note this is different from .git/.gitignore)
update: merge with library developed by ANTONIO PRIVITERA @CINECA IBM CLUSTER.
The modifications, few indeed, should improve portability although important
modifications are still in order in the calling code to run.
UPDATE: big update involving convergence and mainly the introduction of splot/sread routines for
2/3-dim arrays, differentiating with resepct to data_save/read routines, that now can
be invoked separately.
