+     "Writing interfaces to command line software is cumbersome.  The cmdfun
+package provides a framework for building function calls to seamlessly
+interface with shell commands by allowing lazy evaluation of command line
+arguments.  It also provides methods for handling user-specific paths to tool
+installs or secrets like API keys.  Its focus is to equally serve package
+builders who wish to wrap command line software, and to help analysts stay
+inside R when they might usually leave to execute non-R software.")
