/********************************* routerparse.c ************************/
+#define MAX_STATUS_TAG_LEN 32
+/** Structure to hold parsed Tor versions. This is a little messier
+ * than we would like it to be, because we changed version schemes with 0.1.0.
+ *
+ * Before 0.1.0, versions were of the format:
+ * MAJOR.MINOR.MICRO(status(PATCHLEVEL))?(-cvs)?
+ * where MAJOR, MINOR, MICRO, and PATCHLEVEL are numbers, status is one of
+ * "pre" (for an alpha release), "rc" (for a release candidate), or "." for a
+ * release. As a special case, "a.b.c" was equivalent to "a.b.c.0". We
+ * compare the elements in order (major, minor, micro, status, patchlevel,
+ * cvs), with "cvs" preceding non-cvs.
+ *
+ * We would start each development branch with a final version in mind: say,
+ * "0.0.8". Our first pre-release would be "0.0.8pre1", followed by (for
+ * example) "0.0.8pre2-cvs", "0.0.8pre2", "0.0.8pre3-cvs", "0.0.8rc1",
+ * "0.0.8rc2-cvs", and "0.0.8rc2". Finally, we'd release 0.0.8. The stable
+ * CVS branch would then be versioned "0.0.8.1-cvs", and any eventual bugfix
+ * release would be "0.0.8.1".
+ *
+ * After 0.1.0, versions are of the format:
+ * MAJOR.MINOR.MICRO(.PATCHLEVEL([-.]status_tag)?)?
+ * As before, MAJOR, MINOR, MICRO, and PATCHLEVEL are numbers, with an absent
+ * number equivalent to 0. All versions _should_ be distinguishable purely by
+ * those four numbers; the status tag is purely informational. If we *do*
+ * encounter two versions that differ only by status tag, we compare them
+ * lexically.
+ *
+ * Now, we start each development branch with (say) 0.1.1.1-cvs. The
+ * patchlevel increments consistently as the status tag changes, for example,
+ * as in: 0.1.1.2-alpha, 0.1.1.3-cvs, 0.1.1.4-alpha, 0.1.1.5-cvs, 0.1.1.6-rc
+ * 0.1.1.7-cvs, 0.1.1.8-rc, 0.1.1.9-cvs. Eventually, we release 0.1.1.10.
+ * The stable CVS repository gets the version 0.1.1.11-maint_cvs; the
+ * next patch release is 0.1.1.12.
