# This script fixes several issues:
|
||
|
|
# 1. The fmt files contain timestamps
|
||
|
|
# 2. The fmt files randomly select the path to language.dat.lua and language.def
|
||
|
|
# (/var/lib/texmf/tex/generic/config vs /usr/share/texlive/texmf-dist/tex/generic/config)
|
||
|
|
# 3. The fmt files have a random order due to the way iterators work in lua
|
||
|
|
# The function 'exception_strings' uses these iterators
