Build a given SCons application, applying all of PHASES in order.

Read the reference graph as produced by #:references-graphs from PORT and return it as a list of <store-info> records in topological order--i.e., leaves come first. IOW, store items in the resulting list can be registered in the order in which they appear.

The reference graph format consists of sequences of lines like this:

FILE DERIVER NUMBER-OF-REFERENCES REF1 ... REFN

It is meant as an internal format.

Return the size in bytes of FILE, entering it if FILE is a directory.

Populate the store under directory TARGET with the items specified in REFERENCE-GRAPHS, a list of reference-graph files. Items copied to TARGET maintain timestamps and permissions. When DEDUPLICATE? is true, deduplicate regular files as they are copied to TARGET.

Return an estimate of the size of the closure described by REFERENCE-GRAPHS, a list of reference-graph files.

Copy ITEM, a store item, to the store under TARGET, the target root directory. When DEDUPLICATE? is true, deduplicate it within TARGET.

Fetch REVISION from URL into DIRECTORY. REVISION must be an integer, and a valid Subversion revision. Return #t on success, #f otherwise.

Return #t if the block DEVICE is in use, #f otherwise. This is inspired from fdisk_device_is_used function of util-linux. This is particularly useful for devices that do not appear in /proc/self/mounts like overlayfs lowerdir backend device.

Return the <termios> structure for the tty at FD.
