Since SPMS accepts an arbitrary directory arrangement, existing software
packages can be converted into projects with minimal reorganization. For
example, the Fortran 77 compiler project shown in figure 12 was brought
under project control by the following commands.
.KF
.sp 20
.SM
.ce

The directory aliasing feature of SPMS is also demonstrated by this example.
Sometimes a project will have more than one directory with the same name
as is the case with the Fortran project, where
the name of the `src/f77' compiler driver program directory coincides with the
name of the `doc/f77' documentation directory. Since SPMS insists that
the directories within each project have unique names, the `doc/f77' directory
is aliased to `doc' using \fIpmkdir \-N\fR.
