pp_op_howto formats instructions on how to get more information about an operation. This is "b0-log --id %d".

pp_leveled_feedback ~sep ~op_howto ~output_op_level ~output_ui_level ~level ppf is formatter for memo feedback:

• level indicates the wanted feedback level, this is typically the current B0_std.Log.level. The following levels are treated specially (other arguments can be ignored):

  • B0_std.Log.level.Quiet formats nothing.
  • B0_std.Log.level.Debug report all completed operations with B0_zero_conv.Op.pp_line_and_ui.
• If level >= output_op_level any completed operation gets logged with B0_zero_conv.Op.pp_line_and_ui
• If level >= output_ui_ui any completed operation gets logged with B0_zero_conv.Op.pp_ui
• sep is formatted at the end iff something is formated. Defaults to B0_std.Fmt.cut.

The formatter op_howto should format a way to got more information about an operation, default to pp_op_howto.

TODO. It's a bit unclear what "ui" is here.

trash_dirname is ".trash", a suggested trash directoy name.

get_jobs ~jobs determines a maximal number of spawns. If jobs is None then B0_std.Os.Cpu.logical_count is used.

jobs is a cli interface for specifying the maximal number of commands to spawn concurrently.

• opts are the cli options to specify it, defaults to ["j";"jobs"].
• docs is where the option is documented, defaults to Cmdliner.Manpage.s_common_options
• doc is a doc string.
• doc_none describes how the value is determined if the term is evaluates to None.
• env is a variable that can be used to override the default value, defaults to jobs_var.

jobs_env is "B0_JOBS".
