# Cleaning RevDeBug instrumentation

You may instrument your files as many times as you like. The first time you do this the originals are copied to the revdsrc/ parallel directory tree and each subsequent time they are instrumented from there.\
\
This means that if you want to edit your original source file after instrumenting you should do it in the revdsrc/ subdirectory. When you execute `revd --remove` the source files are copied back from this subdirectory to their original location along with any changes you made in the revdsrc/ tree.

In order to clean your files of any instrumentation, simply use the `--clean` command line switch. 

You can use this with individual files or projects, so for example this will clean all files in the current directory:

```
revd --clean *.js
```

This will clean all files belonging to .project1.

```
revd --clean .project1
```

Cleaning will not remove the files from the revdsrc/ directory tree however. If you wish to revert ALL files to their original state and remove all traces of RevDeBug instrumentation then execute:

```
revd --remove
```
