0. What is this?

****************

This package contains the DustEMWrap v4.3 software, developed and maintained at the Institute of Research in Astrophysics and Planetology (IRAP).

DustemWrap requires the fortran code DustEM, which is developed and maintained at the Institute of Space Astrophysics (IAS). The DustEM fortran code must be downloaded separately (see the DustEMWrap Users' Guide for instructions about obtaining and installing DustEM.) 

More information, including a Users' Guide, is available at the DustEMWrap website, http://dustemwrap.irap.omp.eu

A non-exhaustive list of information on the website : 
* instructions for obtaining DustEM
* installation instructions for the current releases of DustEMWrap and DustEM
* an overview of how DustEMWrap works, including how it interacts with the underlying DustEM fortran code

* format requirements for user input 

* a description of how color corrections and plugins are implemented in DustEMWrap
* a description of the individual DustEMWrap routines

* step-by-step examples 
* patches, minor updates
* FAQ and list of current known issues
