pacwrap

.SH
SYNOPSIS\fR
pacwrap [\fBOPERATION\fR | \fBVERB\fR] [\fBARGUMENTS\fR] [\fBTARGETS\fR]	

.SH
DESCRIPTION\fR
.PP
A package management front-end which utilises libalpm to facilitate the creation of unprivileged, 
namespace containers with parallelised, filesystem-agnostic deduplication. These containers
are constructed with bubblewrap to execute package transactions and launch applications.

.PP
This application is designed to allow for the creation and execution of secure, replicable 
containerised environments for general-purpose use. CLI and GUI applications are all supported. 
Once a container environment is configured, it can be re-established or replicated on any system. 

.PP
Each long-option parameter can also be specified herein as a command verb for a matter of convenience.
Additional command verb shortcuts are available and are documented alongside their relevancy.

.SH

.TP
\fB-C, --compose\fR

.TP
\fB-h, --help\fR <\fBOPERATION\fR | \fBVERB\fR | \fBTOPIC\fR>
Print the help manual to \fBSTDOUT\fR.

.SH
EXECUTE\fR
.PP
Invoke a container to execute the provided command sequence. Command verb \fB`run`\fR provides a 
shortcut to this module.

.TP
\fB<CONTAINER> <CMD>\fR
Container name to spawn an instance of, along with the proceeding command-line sequence to execute.
execute. All command-line parameters after the container name are passed through to execute inside
of the container environment.

.TP
\fB-s, --shell\fR
Invoke a bash shell in the target container. Command verb \fB`shell`\fR provides a shortcut
to this module with this option.

.TP
\fB-r, --root\fR
Execute the provided command sequence with fakeroot and fakechroot.
	
.SS
EXAMPLES\fR
.TP
`$ pacwrap run firefox firefox`
Launch firefox inside an instance of the firefox container.

.TP
`$ pacwrap shell -r base`
Open a fakeroot bash shell inside an instance of the base container.

.SH
SYNCHRONIZATION\fR
.PP
Provides the facilities required to be able to synchronize and create containers in aggregate. 

.TP
\fB-y, --refresh\fR
Synchronize remote package databases. Specify up to 2 times to force a refresh.

.TP
\fB-u, --upgrade\fR
Execute aggregate upgrade routine on all or specified containers. Use \fB`-t, --target[=CONTAINER]`\fR followed
by a list of packages to specify package targets. Packages applicable to a target \fBmust\fR only be specified 
after the target operand.

.TP
\fB-c, --create\fR
Create a container with the first specified target. A container type argument is also required. Command verb 
\fB`init`\fR provides a shortcut to the synchronization module, equivalent to specifying the options \fB`-Syuc`\fR.

.TP
\fB-b, --base\fR
Base container type. Specify alongside \fB`-c, --create`\fR to assign this container type during creation.

This container type is used as the base layer for all downstream containers. Only one base container 
dependency per slice or aggregate is supported. Filesystem and package deduplication via slices and 
aggregate containers are recommended, but optional. This container type is not dependant.

.TP
\fB-s, --slice\fR
Slice container type. Specify alongside \fB`-c, --create`\fR to assign this container type during creation.

Requires a base dependency, and optionally one or more sliced dependencies, to ascertain foreign
packages and influence ordering of downstream synchronization target(s). Container slicing provides
the ability to install packages in a lightweight, sliced filesytem, which aid in the deduplication 
of common downstream package and filesystem dependencies.

Useful for graphics drivers, graphical toolkits, fonts, etc.; these are not meant for applications.

.TP
\fB-a, --aggegrate\fR
Aggregate container type. Specify alongside \fB`-c, --create`\fR to this assign container type during creation.

Requires a base dependency, and optionally one or more sliced dependencies, in order to acertain foreign
packages and amalgamate the target. These containers are ideal for installing software with the aid of
filesystem and package deduplication. 

Useful for all general purpose applications, browsers, e-mail clients, or even terminal user interface 
applications such as IRC clients. It is recommended to base your containers on aggregate type containers.

.TP
\fB-t, --target\fR <\fBCONTAINER\fR> <..\fBPACKAGE\fR>
Declare a target container for the specified operation, followed by a list of package target(s).

.TP
\fB-f, --filesystem\fR
Force execution of filesystem synchronization target on all or specified containers. In combination 
with \fB-o/--target-only\fR, in addition to no other specified targets, filesystems will be synchronized 
without package synhcronization on on all applicable containers. This operation is useful for propagation 
of manual filesystem changes to all aggregate containers.

.TP
\fB-o, --target-only\fR
Apply specified operation on the specified target(s) only.

.TP
\fB-d, --dep\fR <\fBCONTAINER\fR>
Specify dependencies for a container create operation.

.TP
\fB-p, --preview\fR
Perform a dryrun operation on existing containers to preview changes applicable or otherwise specified.
Only applicable to pre-existing targets and not create operations.

.TP
\fB--force-foreign\fR
Force synchronization of foreign packages on resident container. Useful for when installing 
a new package in an aggregate container without all the prerequisite foreign dependencies
synchronized to the resident container's package database.

.TP
\fB--dbonly\fR
Transact on resident containers with a database-only transaction.

.TP
\fB--noconfirm\fR
Override confirmation prompts and confirm all operations.

.SS
EXAMPLES\fR
.TP
`$ pacwrap init --base --target base`
Synchronize remotes and create a base-type container named `base` with no additional packages.

.TP
`$ pacwrap -Syucst common gtk3 qt6-base --dep=base -st nvidia nvidia-utils --dep=base,common`
Synchronize remote databases, create two sliced containers, one named `common` with the packages 
`gtk3`, `qt6-base`, and another named `nvidia` with the package `nvidia-utils`.

.TP
`$ pacwrap -Syucat mozilla firefox --dep=base,common,nvidia`
Synchronize remote databases and upgrade container dependencies, then create aggregate container 
named `mozilla` with the package `firefox`.

.TP
`$ pacwrap -Sot mozilla thunderbird`
Install `thunderbird` in the target container `mozilla`.

.TP
`$ pacwrap -Sof`
Synchronize filesystem state of all associated containers present in the data directory.

.SH
REMOVE\fR
.PP
Remove packages from specified containers.

.TP
\fB-s, --recursive\fR

not apply to packages upstream of a downstream container.

.TP
\fB-c, --cascade\fR
Remove all target packages with the associated target container, including all their 
associated dependencies, provided they are not required by other packages, and are not
marked as being upstream of the target container.

.TP
\fB-t, --target\fR <\fBCONTAINER\fR>
Specify a target container for the specified operation. At least one container target is 
is required for package removal operations.

.TP
\fB--force-foreign\fR
Force the removal of foreign packages on target container. Useful for cleaning up
the package database of foreign, upstream dependencies synchronized to the target
container's package database.

.TP
\fB-m, --delete\fR
Delete root filesystem(s) of specified targets. Shortcout to \fB-Ur\fR.

.TP
\fB-p, --preview\fR
Preview operation and perform no transaction.

.TP
\fB--dbonly\fR

.TP
\fB--noconfirm\fR
Override confirmation prompts and confirm all operations.

.SS

`$ pacwrap -Rt firefox firefox`
Remove the target package firefox from target container firefox.

.TP
`$ pacwrap rm firefox`

will be deleted and the container will be composited from the configuration data enumerated.

.TP
\fB-t, --target=\fR <\fBCONTAINER\fR>

.TP
\fB-f, --force\fR

circumstances, configuration data will only be populated from containers with configuration
data and an associative container root present. This option engages an alternate enuermation 
pathway to allow composition of dormant, uninitialized container configurations.

.TP
\fB--noconfirm\fR
Override confirmation prompts and confirm all operations.

.SS
