I maintain library crates that need to modify the superordinate program project. For example, on Windows, the remoteio crate post-fetch script needs to copy hidapi.dll to the bin/ directory for alr run to work successfully.

With alr 2.0, there is no obvious way for a post-fetch script to find the program project directory. If I run alr printenv in the program project directory mytest/, the resulting export MYTEST_ALIRE_PREFIX="C:\Users\pmunts\mytest" points to the program project directory, but I really need something like export PROGRAM_DIRECTORY="C:\Users\pmunts\mytest" that doesn't require a priori knowledge of the program name.

The required information is also in GPR_PROJECT_PATH, but its contents differs between Linux and Windows, both in format and position of the program project directory.
