// TODO: implement
// Use yaml-rust with "preserve-order" = true
// Strategy:
// 1. Backup the current config directory in a zip archive (also with the packages)
// 2. Create a temporary directory alonside the legacy one called "espanso-new"
// 3. Convert all the files and write the output into "espanso-new"
// 4. Rename the legacy dir to "espanso-old"
// 5. Rename new dir to "espanso"
// 6. If the legacy directory was a symlink, try to recreate it (ask the user first)

// TODO: before attempting the migration strategy, check if the current
// espanso config directory is a symlink and, if so, attempt to remap
// the symlink with the new dir (after asking the user)
// This is necessary because in order to be safe, the migration strategy
// creates the new config on a new temporary directory and then "swaps"
// the old with the new one

// TODO: test case with packages

// TODO: keep other non-standard directories such as "images/" and "script/"

// TODO: test also with non-lowercase file names

// TODO: test packages in another directory
