# Takes a directory that contains a changes.txt file and
# difference files with names <endf-file>.diff.html.
# The file changes.txt contains the output of
# 'git diff --name-status commit1 commit2', thus the first
# column contains the modification type ((A)dded, (M)odified, (D)eleted)
# and the second column the <endf-file> names relative to the root
# of the fendl-endf repository. This result of this script is an
# output file diff.html with an html-table with links to the 
# <endf-file>.diff.html files.
# 
# Usage:
#     python create_sublib_difftable.py <dir>
#
#     <dir>: directory with changes.txt and differences files 
#
#     Following environment variables must be set:
#
#       FENDL_TEMPLATE_DIR - folder with html templates
#       FENDL_VERSION - version of FENDL library
#       FENDL_OLD_VERSION - previous version of FENDL library
