The basic idea behind a compiler abstraction class is that each

instance can be used for all the compile/link steps in building
|

a single project. Thus, attributes common to all of those compile
|
|
and link steps -- include directories, macros to define, libraries
|
|
to link against, etc. -- are attributes of the compiler instance.
|
|
To allow for variability in how individual files are treated,

most (all?) of those attributes may be varied on a per-compilation

|
or per-link basis."""
