+ * pr_log - print things with varying levels of importance
+ *
+ * pr_log is a "logger" styled similarly to Linux's printk() and pr_*() macros.
+ * The amount of debug output is controlled by the value of the `DEBUG`
+ * environment variable.
+ *
+ * It provides work-alikes for Linux's pr_devel, pr_debug, pr_info, etc macros.
+ *
+ * Example:
+ * #include <ccan/pr_log/pr_log.h>
+ *
+ * int main(int argc, char *argv[])
+ * {
+ * pr_debug("It's working\n");
+ * pr_info("Really, it works\n");
+ * pr_emerg("I'm serious %d\n", argc);
+ * return 0;
+ * }
