-A dependency alias (created in populated_depend_aliases) is some name (such as
-java) and some associated run and build time dependencies, specified like this:
-
- alias_build java openjdk-6-jdk
- alias_build java libgcj9-dev
- alias_run java openjdk-6-jre
-
-So when cran2deb needs to use the 'java' build dependency, it will add
-"openjdk-6-jdk, libgcj9-dev" to the Build-Depends:. alias_run deals with
-Depends: only.
-Since in Debian you cannot Build-Depend: upon build-essential, there is a
-special 'ignore' dependency alias (this can be handy for dropping unnecessary
-system requirements)
-
- alias_build ignore build-essential
-
-populate_forcedep contains like:
-
- force java rJava
-
-which forces the R package rJava to use the dependency alias 'java'. This is
-for cases where there is no SystemRequirement.
-
-Finally, populate_sysreq has lines like:
-
- sysreq quantlib quantlib%
-
-This says, whenever a part of a SystemRequirement matches the SQL LIKE pattern
-'quantlib%', use the dependency alias. SystemRequirements are converted to
-lower case and messed around with; details are in R/debcontrol.R in the
-sysreqs_as_debian function. R/debcontrol.R contains pretty much all of the code
-for dependencies (the database interface code is in R/db.R).
