asfsmd - 1.4.1-2 main

Small Python tool (`asfsmd`) that allows one to download XML
files containing Sentinel-1 products metadata from the ASF
archive.
.
Sentinel-1 products are stored in the ASF arcive as ZIP files
that are quite large because they contain both the products
annotations and the binary image data.
.
The `asfsmd` tool is able to retrieve only the relatively samll
annotation files (in XML format) without downloading the entire
ZIP archive.
.
`asfsmd` exploits Python packages like `fsspec` or `httpio` for
reading HTTP resources as random-access file-like objects.
In order to do it the remote server must support the `Range`
header.
.
This approach allows one to open the ZIP archive remotely, inspects
contents, and download only the pieces of data that are actually
necessary to the user.
.
Performnces of this approach are quite poor but, in the specific
case of Sentinel-1 products, the entire process results to be
faster than downloading the entire ZIP archive and extracting only
annotation files.
.
This package contains the command line tool for asfsmd.
