lib/runscripts/datasrc_dir.run: import(): use new schema/make, schema/rm

lib/runscripts/datasrc_dir.run: added schema/rm(), schema/make()

*{.sh,run}: stderr_matches() wrapper calls: removed no longer needed prep_try/rethrow

*{.sh,run}: use new begin_target instead of `echo_func; set_make_vars`

lib/runscripts/datasrc_dir.run: documented how to reinstall staging tables (`rm=1 .../run import`)

bugfix: *{.sh,run}: stderr_matches() wrapper callers: use the required wrapper caller usage, which now includes rethrow and prep_try

lib/runscripts/datasrc_dir.run: removed postprocess(), which now does the same thing its auto-forwarded equivalent would

lib/runscripts/datasrc_dir.run: removed separate @table_subdirs, because the table-only targets can now safely be invoked on all subdirs, being auto-ignored in subdirs that don't support them

lib/runscripts/datasrc_dir.run: use new fwd_self alias

lib/runscripts/datasrc_dir.run: enable $auto_fwd, to create the functionality of lib/forwarding.Makefile's `%` target

moved everything into /trunk/ to create the standard svn layout, for use with tools that require this (eg. git-svn). IMPORTANT: do NOT do an `svn up`. instead, re-use your working copy's existing files with `svn switch` (http://svnbook.red-bean.com/en/1.6/svn.ref.svn.c.switch.html).

bugfix: lib/runscripts/datasrc_dir.run: import(): don't run `sql/install` if the schema already exists, because this will try to rerun all the schema-creation queries. note that this idempotent functionality was not provided by the `make .../install` target that was previously used (idempotency is new with new-style import).

bugfix: lib/runscripts/datasrc_dir.run: import(): can't run `datasrc_make reinstall` anymore because this now defers to the runscript for new-style import datasources (which was done so that `make .../install` properly reinstalls all the datasources). instead, call the applicable make targets manually (there are just 2 of them).

lib/runscripts/datasrc_dir.run: import(): added remake (rm=1) mode that reinstalls the datasource before continuing with the subdirs' import actions

lib/runscripts/datasrc_dir.run: added postprocess target to run postprocess in just the table subdirs, skipping any additional subdirs that don't have this target

lib/runscripts/datasrc_dir.run: @subdirs: moved import_order.txt subdirs into separate @table_subdirs, which provides access to just the table subdirs when the user adds other dirs to @subdirs

lib/runscripts/datasrc_dir.run: include of import.run: use .rel instead of `. "$(dirname "${BASH_SOURCE<sup>0</sup>}")"/...`

lib/runscripts/datasrc_dir.run: moved commands related to any runscript in the datasrc dir to new in_datasrc_dir.run

bugfix: lib/runscripts/datasrc_dir.run, subdir.run: need to remove leading . from dir name to get installed schema name, using new dir2schema()

lib/runscripts/datasrc_dir.run, subdir.run: use new lib/sh/datasrc.sh, which contains code in common to both datasrc-related dir runscripts

lib/runscripts/datasrc_dir.run: extend import.run and provide an import() implementation that runs all the runscripts for import_order.txt subdirs

*{.sh,run}: use simpler .rel() instead of `. "$(dirname "${BASH_SOURCE<sup>0</sup>}")"/...` for relative includes

lib/runscripts/table.run, table.run: use new db_make.sh

added lib/runscripts/datasrc_dir.run
