+Usage: $w3_argv0 [options] [search words]...
+Description:
+  Surfraw search Slackware.com packages
+Local options:
+  -v=<version>                  Slackware version (default $SURFRAW_slack_ver).
+                                For .0 releases, include the .0 (eg 14.0, not 14).
+  -C, -cur                      Same as -v=current
+  -32/-i586, -64/-x86_64        Architecture (default -$defarch)
+  -pa, -pkg, -P                 Package search (default)
+  -d, -desc                     Description search
+  -l, -label                    Label search
+  -c, -content                  Content search
+  -s=<sets>                     Search sets, <sets> may consist of:
+                                  e = extra
+                                  P = pasture
+                                  p = patches
+                                  s = slackware
+                                  S = source
+                                  t = testing
+                                Default: $SURFRAW_slack_sets
+  -S, -src                      Search source (same as -c -sS)
+  -a, -all                      Search all sets (same as -s=ePpsSt)
+Notes:
+  - Default version and architecture read from the OS (/etc/slackware-version
+    and uname -m). You can hardcode them in ~/.config/surfraw/conf (see below).
+  - Search modes: "package" looks at package names, "description"
+    looks at the .txt files named after the packages (created from the
+    slack-desc), "label" looks at the first line of .txt file, and "content"
+    looks at the contents of packages.
+  - "content" searches are for finding out which package a file belongs to.
+    Be aware that symlinks aren't found by this, although if the symlink
+    exists on the local system, its target will be used instead.
+  - The source search is basically useless without "content" mode. Actually
+    it's pretty useless anyway.
+  - Defaults can be set in the config file "~/.config/surfraw/conf". Example:
+SURFRAW_slack_ver=14.2
+SURFRAW_slack_arch=64
+SURFRAW_slack_mode=package
+SURFRAW_slack_sets=eps
+    For 32-bit architecture (i586), use:
+SURFRAW_slack_arch=""
+    In other words do NOT set it to 32, the only valid values
+    are "64" and "".
