MicrOMEGAs 5.3.35 on Homebrew/CentOS7

In short, change compilers and flags in CalcHEP_src/FlagsForSh:

CC="gcc-12"
CFLAGS="-g -O2 -fcommon -fsigned-char -std=gnu99 -fPIC"

FC="gfortran-12"
FFLAGS="-g -O2 -fno-automatic"

Using MadGraph with Python2/3 virtual environments

One of the problems in the current version of MadGraph5_aMC@NLO (v3.3.0 as of November 2021) is the migration from Python 2 to Python 3 is incomplete, especially, in MadAnalysis 5 (v1.8). Here, we try to set up MadGraph5_aMC@NLO with making virtual environments both for Python 2 and 3, to avoid contaminating the user's environment (though all Python packages you need to install is only six). We assume that reasonably decent versions of Python executables are available (e.g., Python 2.7 and Python 3.7 as MadGraph5_aMC@NLO requires).

Download MadGraph5_aMC@NLO and unpack the files. See https://launchpad.net/mg5amcnlo for the latest version of MadGraph5_aMC@NLO.
```
wget https://launchpad.net/mg5amcnlo/3.0/3.3.x/+download/MG5_aMC_v3.3.0.tar.gz
tar xvf MG5_aMC_v3.3.0.tar.gz
```

I use tmux splits (panes). Inside one of these panes there's a Vim process, and it has its own splits (windows).

In Vim I have key bindings C-h/j/k/l set to switch windows in the given direction. (Vim default mappings for windows switching are the same, but prefixed with C-W.) I'd like to use the same keystrokes for switching tmux panes.

An extra goal that I've solved with a dirty hack is to toggle between last active panes with C-\.

Here's how it should work:

	# remove .DS_Store file from GitHub that MAC OS X creates

	# find and remove .DS_Store
	find . -name .DS_Store -print0 \| xargs -0 git rm -f --ignore-unmatch

	# create .gitignore file, if needed
	touch .gitignore
	echo .DS_Store > .gitignore

	# push changes to GitHub

	diskutil list
	diskutil unmountDisk /dev/disk2
	diskutil eraseDisk FAT32 SANDISK /dev/disk2
