[gentoo-dev] questions of semantics in ebuild.sh

[Drake Wyrm]

When ebuild.sh is called to perform one of the steps of a merge, it mostly
uses one of the dyn_* functions to perform the task. The dyn_* function,
in turn, usually does some prepwork, calls a pkg_* or src_* function,
and does some followup. My questions are in regard to the meaning of
those prefixes. The "pkg_" and "src_" prefixes seem descriptive enough,
but unnecessary. Why were "src_unpack", "src_compile", and "src_install"
chosen vice "pkg_unpack", etc.? What does "dyn" refer to, anyway?

I know these questions probably seem rather pointless, but those names
mean (or meant) something to somebody. I am trying to understand what
the designers of Portage were thinking to help me understand how Portage
works.
