+dnl
+dnl Two optional arguments:

+dnl           if not specified, any version will be accepted.
+dnl           The version should be specified as three numbers,
+dnl           without suffixes. E.g. 4.10.15 or 5.0.3
+dnl   second: force the specified library flavor to be selected,
+dnl           if not specified, a user will be able to choose
+dnl           between client (non-thread-safe) and embedded
+dnl
+dnl On successful execution sets MYSQL_CLIENT_CFLAGS and
+dnl MYSQL_CLIENT_LIBS shell variables and makes substitutions
+dnl out of them (calls AC_SUBST)

+dnl Transformation below works as follows:
+dnl   assume, we have a number 1.2.3-beta
+dnl   *a* line removes the suffix and adds first and last dot to the version:
+dnl             .1.2.3.
+dnl   *b* line adds a 0 to a "single digit surrounded by dots"
+dnl             .01.2.03.
+dnl       note that the pattern that matched .1. has eaten the dot for .2.
+dnl       and 2 still has no 0
+dnl   *c* we repeat the same replacement as in *b*, matching .2. this time
+dnl             .01.02.03.
+dnl   the last replacement removes all dots
+dnl             010203
