3f03f0a447
The change is only relevant to development as all the call to python scripts is done calling C++ os::python that invoques the appropriate python version. The change is two fold, on one hand remove all the uses of /usr/bin/env for python. On the other hand rename all the calls to python from python to python3 making it explicit and being compliant with PEP 394 -- The "python" Command on Unix-Like Systems: https://www.python.org/dev/peps/pep-0394/ Remove the sheebang from src/graphics/GraphicsConverter.cpp because it is not necessary. Some small whitespace changes.

# This script generates a toolbar image for each missing math symbol.
|
|
# It needs the template document generate_symbols_images.lyx for generating
|
|
# the png image via preview.sty and dvipng, or the template document
|
|
# generate_symbols_svg.lyx for generating the SVG image via dvisvgm.
|
|
# Either document must contain the placeholder formula '$a$'.
|
|
# The created images are not always optimal, therefore the existing manually
|
|
# created images should never be replaced by automatically created ones.
