# Purpose: Generate an inventory of all globally installed NPM packages across
# different Node.js versions managed by NVM. This helps when migrating from
# NVM to ASDF or other version managers by documenting what packages were installed.
#
# Output format: PackageName PackageVersion NodeVersion
 
# Ensure NVM is loaded
