 Parse and test a single file by executing the following commands:
 
 ``` sh
-$ cargo run -- parse FILES...
-$ cargo run -- test TESTFILES...
+$ cargo run --features cli -- parse FILES...
+$ cargo run --features cli -- test TESTFILES...
 ```
 
 Additional flags can be passed to these commands as well. For example, to generate
 a visualization for the test, execute:
 
 ``` sh
-$ cargo run -- test -V TESTFILES...
+$ cargo run --features cli -- test -V TESTFILES...
 ```
 
 To generate the visualization regardless of test outcome, execute:
 
 ``` sh
-$ cargo run -- test -V --output-mode=always TESTFILES...
+$ cargo run --features cli -- test -V --output-mode=always TESTFILES...
 ```
