+@findex CONFIGURE_SHELL_COMMAND_PROFREPORT
+
+When building a custom command set, define
+@code{CONFIGURE_SHELL_COMMAND_PROFREPORT} to have this
+command included.
+
+This command can be excluded from the shell command set by
+defining @code{CONFIGURE_SHELL_NO_COMMAND_PROFREPORT} when all
+shell commands have been configured.
+
+@subheading PROGRAMMING INFORMATION:
+
+The configuration structure for the @code{profreport} has the
+following prototype:
