Command flags (OPTIONS) in man pages have to date been in haphazard order. Sometimes that order is sensible, e.g., most-important options first, but more often they're just in arbitrary places. This makes life hard for users. Here, I update the man-page-check Makefile script so it checks and enforces alphabetical order in OPTIONS sections. Then -- the hard part -- update all existing man pages to conform to this requirement. Signed-off-by: Ed Santiago <santiago@redhat.com>

## NAME
|
|
podman\-import - Import a tarball and save it as a filesystem image
|
|
|
|
## SYNOPSIS
|
|
**podman import** [*options*] *path* [*reference*]
|
|
|
|
**podman image import** [*options*] *path* [*reference*]
|
|
|
|
## DESCRIPTION
|
|
**podman import** imports a tarball (.tar, .tar.gz, .tgz, .bzip, .tar.xz, .txz)
|
|
and saves it as a filesystem image. Remote tarballs can be specified using a URL.
|
|
Various image instructions can be configured with the **--change** flag and
|
|
a commit message can be set using the **--message** flag.
|
|
**reference**, if present, is a tag to assign to the image.
|
|
**podman import** is used for importing from the archive generated by **podman export**, that includes the container's filesystem. To import the archive of image layers created by **podman save**, use **podman load**.
