using python to translate fortran90 to julia

This is an ongoing effort to translate FORTRAN90 to Julia. I could use ccall() to simplify my life, but I really need to understand what happens in the original F90 code.

Life is simple here because the array conventions of the two languages are the same.

If you have any questions / suggestions, please open an issue. Your question will help me to improve the code !

NOTE:

1. The file "JulTran.jl" contains necessary Julia structs and macros for the translated code to run.

2. One needs to using Printf explicitly at the beginning of the translated code.

3. Is it meaningfuul to translate ?

Oh, by the way, you still have to manually finalize the translation since:

1. I haven't figured out how to deal with the fabulous FORTRAN GOTO instruction

2. FORTRAN compiler can deal with negative array index if the array is allocated accordingly. I translate the FORTRAN90 do loop literaly even though the iterator may be negative. Please be cautious. I do not want to translate the do loop because I may replace most of them by something like a[:,i] += b in Julia. That can only be accomplished by a human ...

3. Plans

3.1 write a skeleton of each F90 file with empty contents inside functions

3.2 automate the translation of the read(...) ... instructions in the F90 file
