$PROGNAME: [options] <target> [arguments]

Targets: (only one may be specified)

binary-bootstrap [arch]
    Install bootstrap packages from host repositories into <masterdir>.
    If the optional 'arch' argument is set, it will install bootstrap packages
    from this architecture, and its required xbps utilities. The <masterdir>
    will be initialized for chroot operations.

bootstrap
    Build and install from source the bootstrap packages into <masterdir>.

bootstrap-update
    Updates bootstrap packages with latest versions available from registered
    repositories in the XBPS configuration file.

consistency-check
    Runs a consistency check on all packages

chroot
    Enter to the chroot in <masterdir>.

clean-repocache
    Removes obsolete packages from <hostdir>/repocache.

fetch <pkgname>
    Download package source distribution file(s).

extract <pkgname>
    Extract package source distribution file(s) into the build directory.
    By default set to <masterdir>/builddir.

patch <pkgname>
    Patch the package sources and perform other operations required to
    prepare a package for configuring and building

configure <pkgname>
    Configure a package (fetch + extract + patch + configure).

build <pkgname>
    Build package source (fetch + extract + patch + configure + build).

check <pkgname>
    Run the package check(s) after building the package source.

install <pkgname>
    Install target package into <destdir> but not building the binary package
    and not removing build directory for inspection purposes.

pkg <pkgname>
    Build binary package for <pkgname> and all required dependencies.

clean [pkgname]
    Removes auto dependencies, cleans up <masterdir>/builddir and <masterdir>/destdir.
    If <pkgname> argument is specified, package files from <masterdir>/destdir and its
    build directory in <masterdir>/buiddir are removed.

list
    Lists installed packages in <masterdir>.

remove <pkgname>
    Remove target package from <destdir>. If <pkgname>-<version> is not matched
    from build template nothing is removed.

remove-autodeps
    Removes all package dependencies that were installed automatically.

purge-distfiles
    Removes all obsolete distfiles in <hostdir>/sources.

show <pkgname>
    Show information for the specified package.

show-avail <pkgname>
    Returns 0 if package can be built for the given architecture,
    any other error otherwise.

show-build-deps <pkgname>
    Show required build dependencies for <pkgname>.

show-deps <pkgname>
    Show required run-time dependencies for <pkgname>. Package must be
    installed into destdir.

show-files <pkgname>
    Show files installed by <pkgname>. Package must be installed into destdir.

show-hostmakedepends <pkgname>
    Show required host build dependencies for <pkgname>.

show-makedepends <pkgname>
    Show required target build dependencies for <pkgname>.

show-options <pkgname>
    Show available build options by <pkgname>.

show-shlib-provides <pkgname>
    Show list of provided shlibs for <pkgname>. Package must be installed into destdir.

show-shlib-requires <pkgname>
    Show list of required shlibs for <pkgname>. Package must be installed into destdir.

show-var <var>
    Prints the value of <var> if it's defined in xbps-src.

show-repo-updates
    Prints the list of outdated packages in XBPS repositories.

show-sys-updates
    Prints the list of outdated packages in your system.

sort-dependencies <pkg> <pkgN+1> ...
    Given a list of packages specified as additional arguments, a sorted dependency
    list will be returned to stdout.

update-bulk
    Rebuilds all packages in the system repositories that are outdated.

update-sys
    Rebuilds all packages in your system that are outdated and updates them.

update-check <pkgname>
    Check upstream site of <pkgname> for new releases.

update-hash-cache
    Update the hash cache with existing source distfiles.

zap
    Removes a masterdir but preserving ccache, distcc and host directories.

Options:

-a  <target>
    Cross compile packages for this target machine. Supported targets:

$(print_cross_targets)

-C  Do not remove build directory, automatic dependencies and
    package destdir after successful install.

-E  If a binary package exists in a local repository for the target package,
    do not try to build it, exit immediately.

-f  Force running the specified stage (configure/build/install/pkg)
    even if it ran successfully.

-G  Enable XBPS_USE_GIT_REVS (see etc/defaults.conf for more information).

-Q  Enable running the check stage.

-g  Enable building -dbg packages with debugging symbols.

-H  <hostdir>
    Absolute path to a directory to be bind mounted at <masterdir>/host.
    The host directory stores binary packages, sources and package dependencies
    downloaded from remote repositories.
    If unset defaults to void-packages/hostdir.

-h  Usage output.

-I  Ignore required dependencies, useful for extracting/fetching sources.

-j  Number of parallel build jobs to use when building packages.

-L  Disable ASCII colors.

-m  <masterdir>
    Absolute path to a directory to be used as masterdir.
    The masterdir is the main directory to build/store/compile packages.
    If unset defaults to void-packages/masterdir.

-N  Disable use of remote repositories to resolve dependencies.

-o  <opt,~opt2,...>
    Enable or disable (prefixed with ~) package build options. Note this overrides
    options set via XBPS_PKG_OPTIONS from 'etc/conf'. This effectively has the same
    effect than setting 'XBPS_PKG_OPTIONS_<pkgname>' in 'etc/conf'.
    Supported options can be shown with the 'show-options' target.

-r  <repo>
    Use an alternative local repository to store generated binary packages.
    If unset defaults to <hostdir>/binpkgs. If set the binpkgs will
    be stored into <hostdir>/binpkgs/<repo>.
    This alternative repository will also be used to resolve dependencies
    with highest priority order than others.

-t  Create a temporary masterdir to not pollute the current one. Note that
    the existing masterdir must be fully populated with binary-bootstrap first.
    Once the target has finished, this temporary masterdir will be removed.
    This flag requires xbps-uchroot(1).
