./2_gen_diff.sh -h

USAGE: Execute diff/gen_diff.py (to generate diff PDFs) with pipenv support

./2_gen_diff.sh [-h] [-p PY] [-t DIR] [-m TEX] [-k KEYWORD]
                [-b BR] [-a MAX_AU] [-c COMMIT_NUM=1] [-v (1/2/3/4/5/6/7)]:
 [-h]               Show usage
 [-p PY=diff/gdpy]  Change python script path (e.g., '-p zzz/gen_diff.py')
 [-t DIR=diff/]     Change target directory (e.g., '-t abc/'; must end with '/')
 [-m TEX=Paper]     Change Main Tex file (e.g., '-m xyz' use xyz.tex as Main)
 [-k KEYWORD]       Add start word for commit msg (e.g., '-k Add -k Update')
 [-b BR=master]     Set branch for generating diff PDFs
 [-a MAX_AU=2]      Set max author num (require preamble '._p*.tex' for laxdiff)
 [-c COMMIT_NUM=1]  Set start commit num (e.g., '-c 3' starts from 3rd commit)
 [-v]               Verbose mode, show all outputs (for debug)
 [-v 1/2/3/4/5/6/7] Verbose mode for specific command:
                      [1: new-pdflatex, 2: new-bibtex,
                       3: old-pdflatex, 4: old-bibtex,
                       5: latexdiff, 6: diff-pdflatex, 7: diff-paflatex]
