+$SELF v$VERSION - Download the sources for a SlackBuilds.org build.
+(c) 2014, 2023 B. Watson (urchlay@slackware.uk)
+Licensed under the WTFPL: Do WTF you want with this.
+
+Usage: $SELF [-f] <wget-options>
+
+Execute $SELF in the directory that contains the .info and .SlackBuild
+files. If the files are not found in the current directory, they'll be
+looked for in the cache directory, and symlinked to the current dir if
+found there. If they're not in the cache, they'll be downloaded with wget.
+
+Each file's md5sum is checked against the .info file in the current directory.
+
+Options:
+
+-h, --help: Show this help message.
+
+-f: Ignore locally cached files, always download.
+
+-a: Download from sbosrcarch (Source Archive).
+
+Any other options you pass to it will be passed to wget.
+
+By default, --content-disposition is used. If you want to disable it, use
+the --no-content-disposition wget option.
+
+The default cache directory is $DEFCACHEDIR,
+but you can override this by setting SBODL_CACHEDIR in the environment.
+
+If you need to download files for a different architecture
+(e.g. 32-bit files when running on a 64-bit OS), you can override ARCH
+in the environment: "ARCH=i686 sbodl" would download the 32-bit source
+file(s).
