+SYNOPSIS
+      xforall <filepattern> <command>
+
+DESCRIPTION
+      Execute <command> for all matching files. The <command> string can
+      contain replacment marks. Currently there are five of these marks:
+      - "!!" this mark stands for the full file name.
+      - "!e" stands for the extension of the file name.
+      - "!f" stands for the file name without extension and directory name.
+      - "!h" stands for the full directory name of the files.
+      - "!r" stands for the full file name without file extension.
+      - "!t" stands for the file name without the directory name.
+
+      If the full file name would be "/directory/file.ext" then
+      "!!" equals "/directory/file.ext"
+      "!e" equals "ext"
+      "!f" equals "file"
+      "!h" equals "/directory"
+      "!r" equals "/directory/file"
+      "!t" equals "file.ext"
+
