An INSTALL file does not have to be included with the package. An INSTALL file
is utilized for specifying external system requirements needed. It should be
used in combination with the
SystemRequirements field of the Description
file. This file should contain installation instructions
for the required system dependency.
Specifying this requirement does not guarantee that Bioconductor will agree to install the external system requirement. It is encourage to discuss any additional system requirements on the email@example.com before development.
System requirements should never be exclusive to a particular version. Maintainers are expected to have their package work with whatever the current version of external software is available.
