Rationale

DataSHIELD has a complex stack in which problems may creep in at various levels (e.g. a change in the operating system, a shared library, opal, R, other DataSHIELD functions etc). We also have a range of code authors working on variety of platforms. With this in mind we like to check new code works before it is accepted into the main code base, and we like to build the entire stack at regular intervals to make sure nothing has changed underneath us. We do this with continuous integration.
