-LPM is a package manager for `lite-xl`, written in C (and packed-in lua).
-
-It's designed to install packages from our central github repository (and
-affiliated repositories), directly into your lite-xl user directory. It can
-be called independently, for from the lite-xl `plugin_manager` plugin.
-
-LPM will always use https://github.com/lite-xl/lite-xl-plugins as its base
-repository, if none are present, and the cache directory does't exist,
-but others can be added, and this base one can be removed.
-
-It has the following commands:
-
-  lpm init                                 Implicitly called before all commands
-                                           if necessary, but can be called
-                                           independently to save time later.
-  lpm repo list                            List all extant repos.
-  lpm [repo] add <repository remote>       Add a source repository.
-    [...<repository remote>] 
-  lpm [repo] rm <repository remote>        Remove a source repository.
-    [...<repository remote>]
-  lpm [repo] update [<repository remote>]  Update all/the specified repos.
-    [...<repository remote>]        
-  lpm [plugin] install                     Install specific plugins.
-    <plugin name>[:<version>]              If installed, upgrades.
-    [...<plugin name>:<version>]                     
-  lpm [plugin] uninstall <plugin name>     Uninstall the specific plugin.
-    [...<plugin name>]

-Flags have the following effects:
-
-  --json                   Performs all communication in JSON.
-  --userdir=directory      Sets the lite-xl userdir manually.
-                           If omitted, uses the normal lite-xl logic.
-  --cachedir=directory     Sets the directory to store all repositories.
-  --tmpdir=directory       During install, sets the staging area.
-  --verbose                Spits out more information, including intermediate
-                           steps to install and whatnot.
-  --quiet                  Outputs nothing but explicit responses.
-  --mod-version            Sets the mod version of lite-xl to install plugins.
-  --version                Returns version information.
-  --remotes                Automatically adds any specified remotes in the 
-                           repository to the end of the resolution list.
-                           This is a potential security risk, so be careful.
-  --help                   Displays this help text.
-  --ssl_certs              Sets the SSL certificate store.
-  --arch                   Sets the architecture (default: ]] .. _G.ARCH .. [[).
-  --force                  Ignores checksum inconsitencies. 
-                           Not recommended; security risk.
-  --assume-yes             Ignores any prompts, and automatically answers yes
-                           to all.
-  --no-install-optional    On install, anything marked as optional
-                           won't prompt.
