     is useful to get parameters for your `Makefile`, like the last page when
     implementing pagination, see blogc-pagination(7) for details. This option can
     also dump variables defined in a source file, if called without `-l`.
-    Please note that variables generated by blogc during rendering process, like
-    `BLOGC_RUSAGE_MEMORY` are not available, because blogc will exit without
-    rendering any content when called with this option, and will not even require
-    a template. However, variables generated during parsing process, like
-    `CONTENT` are available.
 
   * `-t` <TEMPLATE>:
     Template file. It is a required option, if `blogc` needs to render something.
