+
+__Session:__ Fortran-lang minisymposium (10 min).
+
+__Abstract:__ 
+
+The Fortran-lang stdlib was introduced to provide extensive support to fortran developers by providing modules that can be directly used in thier programs. A list is one of the necessary data structure that has numerous applications.
+The project under Google Summer of Code programme aimed to implement an efficient linked list module that is devoid of any memory leak. The module covers a bunch of APIs that are important in initial phase.
+The Linked list developed is Generic Heterogeneous list i.e. it supports storage of multiple data types in the same list. 
+The APIs can be further explained in detail in presentation with suitable examples.
