-miniexpect is a very simple expect-like library for C.
+Miniexpect is a very simple expect-like library for C.  Expect is a
+way to control an external program that wants to be run interactively.
 
-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.

+Tcl.  It is also thread safe, const-correct and uses modern C
+standards.
 
-It is standalone, except that it requires the PCRE (Perl Compatible
-Regular Expressions) library from http://www.pcre.org/.  The PCRE
-dependency is fundamental because we want to offer the most powerful
-regular expression syntax to match on, but more importantly because
-PCRE has a convenient way to detect partial matches which made this
-library very simple to implement.
