+# `sisyphus`
+
+Sisyphus is a simple python wrapper around portage, gentoolkit, and portage-utils
+which provides an apt-get/yum-alike interface to these commands,
+to assist newcomer people transitioning from Debian/RedHat-based systems to Gentoo.
+
+Use 'sisyphus COMMAND --help' for detailed usage.
+
+**Usage**:
+
+```console
+$ sisyphus [OPTIONS] COMMAND [ARGS]...
+```
+
+**Options**:
+
+* `--install-completion`: Install completion for the current shell.
+* `--show-completion`: Show completion for the current shell, to copy it or customize the installation.
+* `--help`: Show this message and exit.
+
+**Commands**:
+
+* `autoremove`: Uninstall packages that are no longer needed.
+* `branch`: Pull the selected branch of the Portage tree,...
+* `install`: Install binary and/or ebuild(source)...
+* `mirror`: List/Set the active binary repository mirror.
+* `rescue`: Resurrect Sisyphus's package database if lost...
+* `search`: Search for binary and/or ebuild (source)...

+* `upgrade`: Upgrade the system using binary and/or ebuild...
+
+## `sisyphus autoremove`
+
+Uninstall packages that are no longer needed.
+When you uninstall a package without it's reverse dependencies, those dependencies will become orphans if nothing else requires them.
+In addition, a package may no longer depend on another one, so that other package becomes orphan as well if nothing else requires it.
+Use this option to check the whole dependency chain for such packages, and uninstall them.
+
+**Usage**:
+
+```console
+$ sisyphus autoremove [OPTIONS]
+```
+
+**Options**:
+
+* `--help`: Show this message and exit.
+
+## `sisyphus branch`
+
+Pull the selected branch of the Portage tree, Redcore overlay and Portage configs.
+The remote can be selected by using the --remote option.
+
+'BRANCH' can be one of the following : master, next
+
+'REMOTE' can be one of the following : gitlab, pagure (default is pagure)
+
+* Examples:
+
+'branch master --remote=gitlab' will pull the branch 'master' from gitlab.com
+
+'branch next --remote=pagure' will pull the branch 'next' from pagure.io
+
+!!! WARNING !!!
+
+Once you changed the branch, you must pair it with the correct binary repository.
+
+Branch 'master' must be paired with the stable binary repository (odd numbers in 'sisyphus mirror list').
+
+* Examples : 'sisyphus mirror set 1' or 'sisyphus mirror set 5'
+
+Branch 'next' must be paired with the testing binary repository (even numbers in 'sisyphus mirror list').
+
+* Examples : 'sisyphus mirror set 2' or 'sisyphus mirror set 8'
+
+**Usage**:
+
+```console
+$ sisyphus branch [OPTIONS] [master|next]
+```
+
+**Options**:
+
+* `-r, --remote [gitlab|pagure]`
+* `--help`: Show this message and exit.
+
+## `sisyphus install`
+
+Install binary and/or ebuild(source) packages.
+By default, only binary packages will be installed.
+Use the --ebuild option to install ebuild(source) packages.
+
+* Examples:
+
+'sisyphus install pidgin'
+
+will install pidgin binary package (if available); if there is none, but the ebuild(source) package for pidgin is found, it will stop and suggest the --ebuild option.
+
+'sisyphus install pidgin --ebuild'
+
+will compile pidgin from source
+
+The --ebuild option will preffer to reuse binary packages(if available) to satisfy the dependencies for the ebuild(source) package, speeding up the installation.
+You can use the --ebuild option even if you don't want to install any ebuild(source) packages; It will fall back to binary packages only.
+
+**Usage**:
+
+```console
+$ sisyphus install [OPTIONS] PKGNAME...
+```
+
+**Options**:
+
+* `-e, --ebuild`
+* `--help`: Show this message and exit.
+
+## `sisyphus mirror`
+
+List/Set the active binary repository mirror.
+
+**Usage**:
+
+```console
+$ sisyphus mirror [OPTIONS] COMMAND [ARGS]...
+```
+
+**Options**:
+
+* `--help`: Show this message and exit.
+
+**Commands**:
+
+* `list`: List available binary package repository...
+* `set`: Change the binary package repository to the...
+
+### `sisyphus mirror list`
+
+List available binary package repository mirrors (the active one is marked with *).
+
+**Usage**:
+
+```console
+$ sisyphus mirror list [OPTIONS]
+```
+
+**Options**:
+
+* `--help`: Show this message and exit.
+
+### `sisyphus mirror set`
+
+Change the binary package repository to the selected mirror.
+
+**Usage**:
+
+```console
+$ sisyphus mirror set [OPTIONS] INDEX
+```
+
+**Options**:
+
+* `--help`: Show this message and exit.
+
+## `sisyphus rescue`
+
+Resurrect Sisyphus's package database if lost or corrupted.
+If for some reason Sisyphus's package database is lost or corrupted, it can be resurrected using Portage's package database.
+If Portage's package database is corrupted (in this case you're screwed anyway :D), only a partial resurrection will be possible.
+If Portage's package database is intact, full resurrection will be possible.
+
+**Usage**:
+
+```console
+$ sisyphus rescue [OPTIONS]
+```
+
+**Options**:
+
+* `--help`: Show this message and exit.
+
+## `sisyphus search`
+
+Search for binary and/or ebuild (source) packages.
+
+**Usage**:
+
+```console
+$ sisyphus search [OPTIONS] PKGNAME...
+```
+
+**Options**:
+
+* `--help`: Show this message and exit.
+
+## `sisyphus spmsync`
+
+Sync Sisyphus's package database with Portage's package database.
+When you install something with Portage directly (emerge), Sisyphus is not aware of that package, and it doesn't track it in it's database.
+Use this command to synchronize Sisyphus's package database with Portage's package database.
+
+**Usage**:
+
+```console
+$ sisyphus spmsync [OPTIONS]
+```
+
+**Options**:
+
+* `--help`: Show this message and exit.
+
+## `sisyphus sysinfo`
+
+Display information about installed core packages and portage configuration.
+
+**Usage**:
+
+```console
+$ sisyphus sysinfo [OPTIONS]
+```
+
+**Options**:
+
+* `--help`: Show this message and exit.
+
+## `sisyphus uninstall`
+
+Uninstall packages *SAFELY* by checking for reverse dependencies.
+If reverse dependencies exist, the package(s) will NOT be uninstalled to prevent the possible breakage of the system.
+If you really want to uninstall the package, make sure you uninstall all reverse dependencies as well.
+This will not allways be possible, as the reverse dependency chain may be way to long and require you to uninstall critical system packages.
+
+* Examples:
+
+'sisyphus uninstall firefox'
+
+will succeed, nothing depends on it
+
+'sisyphus uninstall pulseaudio'
+
+will fail, many packages depend on it
+
+With --force option, packages are uninstalled *UNSAFELY* by ignoring reverse dependencies.
+This may break your system if you uninstall critical packages.
+It will try the best it can to preserve the libraries required by other packages to prevent such a breakage.
+Upgrading the system may pull the packages back in, to fix the reverse dependency chain.
+
+* Examples :
+
+'sisyphus uninstall pulseaudio --force'
+
+will succeed, but you may no longer have audio
+
+'sisyphus uninstall openrc --force'
+
+will succeed, but the system will be broken
+
+**Usage**:
+
+```console
+$ sisyphus uninstall [OPTIONS] PKGNAME...
+```
+
+**Options**:
+
+* `-f, --force`
+* `--help`: Show this message and exit.
+
+## `sisyphus update`
+
+Update the Portage tree, the Redcore Overlay(s), Portage configs and Sisyphus's package database.
+
+**Usage**:
+
+```console
+$ sisyphus update [OPTIONS]
+```
+
+**Options**:
+
+* `--help`: Show this message and exit.
+
+## `sisyphus upgrade`
+
+Upgrade the system using binary and/or ebuild (source) packages.
+By default, only binary packages will be upgraded.
+However, if you installed any ebuild(source) packages with the '--ebuild' option, it would make sense to upgrade them too.
+Use the --ebuild option to upgrade **EVERYTHING**, binary and/or ebuild(source) packages.
+
+* Examples:
+
+'sisyphus upgrade'
+
+will upgrade the system using binary packages; if any ebuild(source) package upgrade is detected, it will stop and suggest the --ebuild option
+
+'sisyphus upgrade --ebuild'
+
+will upgrade the system using both binary and/or ebuild(source) packages
+
+The --ebuild option will preffer to reuse binary packages(if available) to satisfy the dependencies for the ebuild(source) packages, speeding up the upgrade.
+You can use the --ebuild option even if you don't have any ebuild(source) packages installed; It will fall back to binary packages only.
+
+**Usage**:
+
+```console
+$ sisyphus upgrade [OPTIONS]
+```
+
+**Options**:
+
+* `-e, --ebuild`
+* `--help`: Show this message and exit.
