I understand that Tupfiles are supposed to be independent. That is you
can't guarantee the order in which they are read, and hence the order
that things are added to the database.
There are two steps. Tup first parses the files and generates rules -
this step can be done in any order (or partially, for instance if only
one of many Tupfiles have been modified). The rules are stored in the
.tup/ database file. Then Tup runs the rules, in order, based on a
dependency graph.
During parsing the filesystem is not examined. Rule dependencies are
determined based on the location of a file (either an input or an
output) in the imaginary future filesystem.
If you're only modifying source files, after the initial parse Tup won't
parse the Tupfiles again - it just runs the rules from the database.
