# Fix TL;DR and BP;DR entries.
patch -p1 < $CWD/semicolons.diff

# vera.h includes a non-ASCII character encoded as iso-8859-1. It's
# a multiplication sign. Replace with ASCII letter x. Also replace
# all [[ and ]] with [ and ]. Also, vera.c's first entry is missing
# the @item.
patch -p1 < $CWD/utf8_and_double_brackets.diff

# Next 2 are from Debian:

# This one is actually harmful IMO. It gets rid of the 'Up: Top'
# links at the start of each letters' worth of acronyms.
#patch -p1 < $CWD/01_texinfo_node_menu.diff

# This one makes vera show up in the info directory (so if you just
# type "info", it shows up under Dictionaries in the index).
