-Installs code-server.
-It tries to use the system package manager if possible.
-After successful installation it explains how to start using code-server.
-
-Pass in user@host to install code-server on user@host over ssh.
-The remote host must have internet access.
-${not_curl_usage-}
-Usage:
-
-  $arg0 [--dry-run] [--version X.X.X] [--edge] [--method detect] \
-        [--prefix ~/.local] [--rsh ssh] [user@host]
-
-  --dry-run
-      Echo the commands for the install process without running them.
-
-  --version X.X.X
-      Install a specific version instead of the latest.
-
-  --edge
-      Install the latest edge version instead of the latest stable version.
-
-  --method [detect | standalone]
-      Choose the installation method. Defaults to detect.
-      - detect detects the system package manager and tries to use it.
-        Full reference on the process is further below.
-      - standalone installs a standalone release archive into ~/.local
-        Add ~/.local/bin to your \$PATH to use it.
-
-  --prefix <dir>
-      Sets the prefix used by standalone release archives. Defaults to ~/.local
-      The release is unarchived into ~/.local/lib/code-server-X.X.X
-      and the binary symlinked into ~/.local/bin/code-server
-      To install system wide pass ---prefix=/usr/local
-
-  --rsh <bin>
-      Specifies the remote shell for remote installation. Defaults to ssh.
-
-The detection method works as follows:
-  - Debian, Ubuntu, Raspbian: install the deb package from GitHub.
-  - Fedora, CentOS, RHEL, openSUSE: install the rpm package from GitHub.
-  - Arch Linux: install from the AUR (which pulls releases from GitHub).
-  - FreeBSD, Alpine: install from npm.
-  - macOS: install using Homebrew if installed otherwise install from GitHub.
-  - All others: install the release from GitHub.
-
-We only build releases on GitHub for amd64 and arm64 on Linux and amd64 for
-macOS. When the detection method tries to pull a release from GitHub it will
-fall back to installing from npm when there is no matching release for the
-system's operating system and architecture.
-
-The standalone method will force installion using GitHub releases. It will not
-fall back to npm so on architectures without pre-built releases this will error.
-
-The installer will cache all downloaded assets into ~/.cache/code-server
-
-More installation docs are at https://coder.com/docs/code-server/latest/install

+      Sets the prefix used by standalone release archives. Defaults to ~/.local
+      The release is unarchived into ~/.local/lib/code-server-X.X.X
+      and the binary symlinked into ~/.local/bin/code-server
+      To install system wide pass ---prefix=/usr/local
+
+  --rsh <bin>
+      Specifies the remote shell for remote installation. Defaults to ssh.
+
+The detection method works as follows:
+  - Debian, Ubuntu, Raspbian: install the deb package from GitHub.
+  - Fedora, CentOS, RHEL, openSUSE: install the rpm package from GitHub.
+  - Arch Linux: install from the AUR (which pulls releases from GitHub).
+  - FreeBSD, Alpine: install from npm.
+  - macOS: install using Homebrew if installed otherwise install from GitHub.
+  - All others: install the release from GitHub.
+
+We only build releases on GitHub for amd64 and arm64 on Linux and amd64 for
+macOS. When the detection method tries to pull a release from GitHub it will
+fall back to installing from npm when there is no matching release for the
+system's operating system and architecture.
+
+The standalone method will force installion using GitHub releases. It will not
+fall back to npm so on architectures without pre-built releases this will error.
+
+The installer will cache all downloaded assets into ~/.cache/code-server
