+functions to ease the parsing of @file{.ini}-style configuration files, and
+to write and update them in an efficient @i{diff-minimal} way.  This means that
+if you parse a file, update a single field, and reserialize, that file should
+differ only in the field we changed and @emph{that's it}: field order, 
comments,
+and incidental whitespace will remain unchanged.  The library aims to produce
+human-readable error messages when things go wrong.")
