 Compared to hsrex, this library has the following changes:
 
+* Renamed `re_comp()` to `tere_comp()` and `re_exec()` to `tere_exec()`
+  to avoid collisions with BSD's functions from unistd.h.
 * Native UTF-8 support - no need to convert UTF-8 to UTF-32 first.
   You no longer need to compile a special version of the library.
   It expects Unicode strings by default unless specifying the `REG_RAW`
-  compilation flag.
+  `tere_comp()` compilation flag.
 
 ## TODO
 
 * Hook into the matching algorithm.
   Even though runtime cannot be as catastrophically bad as in pure
-  backtracking engines like PCRE, `re_exec()` calls can still be slow
+  backtracking engines like PCRE, `tere_exec()` calls can still be slow
   on extremely large texts.
   The hook allows interruptions.
 * Expose enough API to swap out the regular expression lexer.
