- specified comma-separated list of build steps, optionally subject
- concerning package name(s) and/or build step(s) to the below modifiers:
-
- Prepend name w/ `*' to automatically include dependencies, `**'
- to forcibly rebuild all dependencies, and `***` to forcibly
- rebuild all packages that depend on the specified package(s).
-
- Prepend step w/ `^' to filter build steps with, `<' or `<='
- to constrain build steps to below or below or equal with, resp.,
- `>' or `>=' to constrain build steps to above or above or equal
- with, resp.
-
- Currently defined build steps are:
- fetch_download, fetch_extract, configure_patch_pre,
- configure_autotools, configure_patch, configure, build,
- install_subdirs, install_make, install_files, install_libs,
- install, install_rpm, and clean.

- Additionally, the following shorthand aliases and pseudo-steps are provided:
- @fetch, @configure, @build, @install, and @clean, and

- -R Ignore build failures, skip printing package logs, and continue
- building (relaxed mode.)
- -v[v[v[v]]] Be verbose; -vv: always print package logs; -vvv: set xtrace
- during package builds; -vvvv: logs fileops.
- --as-needed Don't build unless the midipix_build repository has received
- new commits.
- --debug-minipix Don't strip(1) minipix binaries to facilitate debugging minipix.
- --dump-on-abort Produce package environment dump files on build failure to be
- used in conjuction with pkg_shell.sh script (excludes -R.)
- --reset-state Reset package build step state on exit.
