+## Goals
+
+| Goal                 | Description |
+| -------------------- | ----------- |
+| `replace-file`       | Apply a regular expression pattern against the contents of a file, replacing matches with the regex-compliant replacement text.  The existing file is changed. |
+| `replace-properties` | Apply a regular expression pattern against a set of property values, replacing matches with the regex-compliant replacement text, and storing in new properties. |
+| `replace-property`   | Apply a regular expression pattern against a property value, replacing matches with the regex-compliant replacement text, and storing in a new property. |
+| `replace-text`       | Apply a regular expression pattern against text, replacing matches with the regex-compliant replacement text, and storing in a new property. |
+| `match-file`         | Evaluate a regular expression pattern against the contents of a file, storing the result in a boolean property. |
+| `match-filename`     | Evaluate a regular expression pattern against the name of a file, storing the result in a boolean property. |
+| `match-properties`   | Evaluate a regular expression pattern against a set of property values, storing the result in boolean properties. |
+| `match-property`     | Evaluate a regular expression pattern against a property value, storing the result in a boolean property. |
+| `match-text`         | Evaluate a regular expression pattern against text, storing the result in a boolean property. |
+| `copy-file`          | A convenience goal that copies all files/folders specified in a source path to a target path. |
+| `move-file`          | A convenience goal that moves all files/folders specified in a source path to a target path. |
+
+### Goal: `replace-file`
+
+| Configuration Property | Data Type   | Required | Default | Description |
+| ---------------------- |:-----------:|:--------:| ------- | ----------- |
+| `chunkSize`            | `int`       |          | `1024`  | The streaming buffer/chunk size in bytes, while evaluating the regular expressions.  Adjust for classic speed/memory trade-off.  Be aware that files are processed line-by-line, unless `allowMultiLineMatch` is set to `true`. |
