First release of the package, for publishing on hex.pm.
The SMTP server and the file and HTTP forwarders have been used for more than two years with an Ercogener GenLoc 341e EaseLoc sensor on a farm equipment.
Several receivers (servers) and forwarders may be added in the future; with potential breaking API changes. If you intend to use this package in production, I encourage you to contact me (mail in my profile).
