 Wrapper for PQXX. Needs to link to libpqxx.
 
+"Works for us" -- meaning the tested use cases are limited. Basic SELECT and INSERT work for us with a server on the LAN. Basic exception handling is provided. 
+
+Example shows how to use in conjunction with std::async responding to an ofxButton to gracefully handle background download and completion "notification" harnessing the update() loop.
+
 Tested with:
 
  - arch linux + qtcreator: 
      - $ sudo pacman -S libpqxx 
-     - .qbs: add: 'libpqxx' to of.pkgConfigs[]
+     - in .qbs: add: 'libpqxx' to of.pkgConfigs
      - 
  - macos + Makefile
      - $ brew install libpqxx
-     - confifg.make: add: PROJECT_LDFLAGS+=-lpqxx
+     - in confifg.make: add: PROJECT_LDFLAGS+=-lpqxx
