Comment (by rhaas):

 If we are willing to re-design the parfile syntax, we may want to consider
 using libconfig http://www.hyperrealm.com/libconfig/ (example see here:
 http://www.hyperrealm.com/libconfig/test.cfg.txt) which offers well
 structured, nested configuration files with build in support for int,
 double, string and list-of-type. It also keeps track of which line and
 file each setting comes from and allows the in-memory structure
 representing the settings to be modified.

 If we want to retain the ability to do simply arithmetic in parfiles
 (which I like) then we'd have to declare most of our types as "string" as
 far as the library is concerned. This currently requires double quotes but
 can likely be changed since the end-of-value is indicated by a semicolon
 ";" anyway.
