-miniexpect is a very simple expect-like library
-
-It has a saner interface than libexpect, and doesn't depend on Tcl.
-It is also thread safe, const-correct and uses modern C standards.
-
-It is standalone, except that it requires the PCRE2 (Perl Compatible
-Regular Expressions) library from http://www.pcre.org/.  The PCRE2
-dependency is fundamental because we want to offer the most powerful
-regular expression syntax to match on, but more importantly because
-PCRE2 has a convenient way to detect partial matches which made this
-library very simple to implement.
