-Julia - REQUIRE: packages and julia version number
----------------
-
-To specify dependencies in Julia, include a REQUIRE file.
-
-To specify a version of Julia to be installed, the first line of the file must
-follow the format `julia <version-number>`. For example:
-```
-julia 0.7
-```
-
-To add package dependencies, the rest of the file can include lines that list
-the names of packages you'd like to be installed. For example:
-
-```
-PyPlot
-DataFrames
-```
-
-Note that `IJulia` is installed by default.
-
-These packages will all be installed, and then precompiled via `using`.
