-\subsection{Planning phase}
-
-We use a recursive planning algorith, recursing over Topbloke commit
-sets (ie, sets $\py$ or $\pn$). We'll call the commit set we're
-processing at each step $\pc$. We start with $\pc = \pl$
-where $\pl = \patchof{L}$.
-
-At each recursive step
-we intend to merge all $\set E_{\pc} = \{ E_{\pc,j \ldots} \}$
-and all the direct contributors of $\pc$ (as determined below)
-into the existing git ref for $\pc$, to make $T_{\pc}$.
-The direct contributors of $\pcn$ are the Topbloke commit sets
-corresponding to the tip branches for the direct dependencies of
-$\pc$.
-The sole direct contributor of $\pcy$ is $\pcn$.
-
-\subsubsection{Planning step for $\pc = \pcn$.}
-
-FIXME DEFINE $\set E$
-
-Choose an (arbitrary, but ideally somehow optimal in
-a way not discussed here) ordering of $\set E_{\pc}$, $E_j$ (for
-$j = 1 \ldots m$). Remove from that set (and ordering) any $E_j$ which
-are $\le$ and $\neq$ some other $E_k$.
-
-Initially let $T_{\pc,0}$ be the git ref for $\pcn$. And let
-$\set D_0 = \depsreqof{T_{\pc,0}}$.
-For each $E_j$ starting with $j=1$ choose a corresponding intended
-merge base $M_j$ such that $M_j \le E_j \land M_j \le T_{\pc,j-1}$.
-Calculate $\set D_j$ as the 3-way merge of the sets $\set D_{j-1}$ and
-$\depsreqof{E_j}$ using as a base $\depsreqof{M_j}$. This will
-generate $D_m$ as the putative direct contributors for $\pcn$.
-
-However, the invocation may specify that certain direct dependencies
-are definitely to be included, or excluded. As a result the set
-of actual direct contributors is some arbitrary set of patches.
