+package @code{commado} provides the command @code{\\DoWithCSL}, which applies
+an existing one-parameter macro to each item in a list in which terms are
+separated by commas.
+
+The package @code{filesdo} provides the command @code{\\DoWithBasesExts},
+which runs the single parameter command on each file whose base and extension
+are provided through two comma-separated lists.
+
+These loop'-like commands are (themselves) entirely expandable.")
