### Examples

- A single command-line argument containing a space character.

      <arg value="-l -a" />

- Two separate command-line arguments.

      <arg line="-l -a" />

- A single command-line argument with the value `\dir;\dir2;\dir3` on DOS-based systems and `/dir:/dir2:/dir3` on Unix-like systems.

      <arg path="/dir;/dir2:\dir3" />

#### </arg>

### Examples

- Removes the label called `My Label` from the versioned file called `App.ico` from the project database specified by the `project-database` property.

      <pvcsdeletelabel projectdatabase="${project-database}" versionlabel="My Label">
          <entities>
              <entity name="/App.ico"/>
          </entities>
      </pvcsdeletelabel>

- Removes the label called `My Label` from all files at and below both `folder1` and `folder2` in the project database specified by the `project-database` property.

      <pvcsdeletelabel projectdatabase="${project-database}" versionlabel="My Label" includesubprojects="true">
          <entities>
              <entity name="/folder1"/>
              <entity name="/folder2"/>
