CCS: How do I import a sensor controller project to CCS ?

Tool/software: Code Composer Studio

Hello, 

I am trying to figure out how to import a sensor controller project to CSS. The examples provided have already the .projectspec file ready to import, but how can i create that file out of the source files (sce.lst, scif.c, scif.h, scif_framework.c, scif_framework.h, scif_osal_tirtoos.c, scif_osal_tirtos.h) ?

Thank you.
