-## Please note that the module is called JuliaTikzModule,

-## a module and a function in the module.
+Enables Julia code and Tikz code to coexist in the same file.
 
+### JuliaTikz
 
+    JuliaTikz(tikzfile,delete=true)
+
+Extract and run the Julia part of a combined tikz/Julia file.
+
+The boundary between the two is the string
+ 
+    \\endinput Julia <name>
+
+where `<name>` is the name that will be given to the Julia file 
+(with .jl appended), and also to a variable `name` in the program,
+i.e. name = "<name>".
+
+The Julia file will be extracted to a temporary directory, which will be 
+deleted  after the run unless the optional argument `delete` is false.
+
+### printcsv
+
+    printcsv(data::Array{Any}, csv="")
+
+Print the array `data` to a file suitable for inclusion in pgfplots.
+The columns of `data` should have a string as first element, and Float64
+as the remaining elements.
+
+The default name of the file will be `<name>.csv`, where `<name>` is the value
+of the global variable `name`, typically given by `JuliaTikz`. Another name may 
+be specified whith the second argument of `printcsv`.
