/**
 * The ExecPermission class represents permission for rmid to execute
 * a specific command to launch an activation group.  An ExecPermission
 * consists of a pathname of a command to launch an activation group.
 * <P>
 * Pathname is the pathname of the file or directory to grant rmid
 * execute permission.  A pathname that ends in "/*" (where "/" is
 * the file separator character, <code>File.separatorChar</code>) indicates
 * all the files and directories contained in that directory. A pathname
 * that ends with "/-" indicates (recursively) all files
 * and subdirectories contained in that directory. A pathname consisting of
 * the special token "{@code <<ALL FILES>>}" matches <b>any</b> file.
 * <P>
 * Note: A pathname consisting of a single "*" indicates all the files
 * in the current directory, while a pathname consisting of a single "-"
 * indicates all the files in the current directory and
 * (recursively) all files and subdirectories contained in the current
 * directory.
