 Actions support several variable substitution features for cross-platform compatibility:
 
 - **`{{deps}}`** - Replaced with the full classpath of all dependencies
-- **`{/}`** - Replaced with the file separator (`\` on Windows, `/` on Unix)
-- **`{:}`** - Replaced with the path separator (`;` on Windows, `:` on Unix)
+- **`{/}`** - Replaced with the file separator (`\` on Windows, `/` on Linux/Mac)
+- **`{:}`** - Replaced with the path separator (`;` on Windows, `:` on Linux/Mac)
+- **`{~}`** - Replaced with the user's home directory (The actual path on Windows, `~` on Linux/Mac)
 - **`{./path/to/file}`** - Converts relative paths to platform-specific format
-- **`{~/path/to/file}`** - Converts home directory paths to platform-specific format
+- **`{./libs:./ext:~/usrlibs}`** - Converts entire class paths to platform-specific format

-### Performance Optimization
+NB: The `{{deps}}` variable substitution is only performed when needed - if your action doesn't contain `{{deps}}`, jpm won't resolve the classpath, making execution faster for simple actions that don't require dependencies.

+NB2: These actions are just a very simple convenience feature. For a much more full-featured cross-platform action runner I recommend taking a look at:
