+    Show the value of a variable right after the source parsing and exits. This
+    is useful to get parameters for your `Makefile`, like the last page when
+    implementing pagination, see blogc-pagination(7) for details. This can be
+    also useful to dump variables defined in a source file without parsing it
+    manually, 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, but variables generated during
+    parsing process, like `CONTENT` are available.
 
   * `-t` <TEMPLATE>:
     Template file. It is a required option, if `blogc` needs to render something.
