csb

#!/bin/sh

# Build and move cscope and etags (or ctags) database to $HOME/.cstags_dir/
#
# Always use `set nocscoperelative` in vim as this script changes path of cscope
# database and absolute path is needed.
#
# Usage:
#
#   * `csb ~/esp/esp-idf/ ../dwm/ ../dmneu/ ~/repo/st` (give directories as input)
#   * `csb`                    (build from current directory)
#
# This will create a cscope database for directories and place it in
# `$HOME/.cstags_dir/`.
