 Usually you want to search for a specific package. This can be done with the `search` command:

 To determine which versions of libjpeg are available to install, issue the `info` command:

 Installing dependencies is just as straightforward. First just create the `subprojects` directory at the top of your source tree and issue the install command.
 
-    # wraptool install libjpeg
+    $ wraptool install libjpeg
     Installed libjpeg branch 9a revision 2
 
 Now you can issue a `subproject('libjpeg')` in your `meson.build` file to use it.
 
 To check if your projects are up to date you can issue the `status` command.

 In this case `zlib` has a newer release available. Updating it is straightforward:
 
-    # wraptool.py update zlib
+    $ wraptool.py update zlib
     Updated zlib to branch 1.2.8 revision 4
 
 Wraptool can do other things besides these. Documentation for these can be found in the command line help, which can be accessed by `wraptool --help`.
