+ 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.
