# No cellname args: default is to process just all non-writable cells.

# Limitation: Explicit named cell created in-mem, never saved, won't scratchify.

#
# -cleanup: Last scratch-dir, if any, and contents are deleted first.
# No restoring old filepath of cells, save after cleanup will fail.
#
# Caller strongly recommended to first do: 'select top cell; expand'
# to force whole hier. of a topcell to be loaded from disk into memory.
#
# This proc does not force expand cells. Before expanded, cells cannot be
# checked whether writable, and cannot have filepath changed.
#
# For batch DRC, for 'drc listall count', every cell in-memory must
# appear writable. This is the work-around (caller to 1st ensure
# hier. is loaded): Reset filepath of readonly cells to a scratch dir,
# make a dummy/empty .mag in scratch dir for each cell. Change cell's
# writeable flag.
#
# Skipped cells:
# In all cases, cells are skipped if
# 'cellname filepath' matches ::scratchWritableDir (already scratchified),
# This proc does NOT try and force expand; it presumes caller forced an expand
# thus cells are skipped if:
# 'cellname filepath' is "default" (can mean not expanded yet, or created never saved),
# 'cellname filepath' is <CELLNAME>.mag, indicates failed expand (unbound).
# Note: when filepath gives "default" or <CELLNAME>.mag, the writeable check not meaningful.

# scratchWritable {*}[cellname list allcells]
#
# TODO: use a combo of filepath & flags likely can detect created in-mem,
# and could redirect those too scratch dir if named explicitly.
#
# Side-effects:
# Runs zero or one subprocess, '/bin/mktemp -d' to make a scratch dir.
# Redirects where newly modified cells would be saved, if they ever are saved.
# Make's a scratch dir that needs to be cleaned-up.
# Leaves empty *.mag files in that scratch dir.
