direnv - 2.32.1-2+b14 main

direnv is an environment variable manager for your shell. It knows
how to hook into bash, zsh and fish shell to load or unload
environment variables depending on your current directory. This
allows one to have project-specific environment variables and not
clutter the "~/.profile" file.
.
Before each prompt it checks for the existence of an ".envrc" file in
the current and parent directories. If the file exists, it is loaded
into a bash sub-shell and all exported variables are then captured by
direnv and then made available to your shell.
.
Because direnv is compiled into a single static executable it is fast
enough to be unnoticeable on each prompt. It is also language
agnostic and can be used to build solutions similar to rbenv, pyenv,
phpenv, ...
