+searchproviders2html.sh
+=======================
+
+This script converts KDE/Konqueror's search providers (a.k.a. web shortcuts),
+that are stored as `.desktop` files, into a Firefox-friendly HTML bookmarks
+file, ready to be imported with Firefox's bookmark manager. Imported bookmarks
+will be in the "Search providers" directory.
+
+The HTML is printed on the standard output, so you'll have to redirect it to a
+file, such as:
+
+    searchproviders2html >searchproviders.html
+
+If your `.desktop` files are not stored at the default location, or if this
+script becomes out of date and the default location is wrong, you can define
+the `SEARCHPROVIDERS_PATH` variable in the environment:
+
+    SEARCHPROVIDERS_PATH=/my/search/providers/directory
+
+Limitations:
+
+- Only the `\{@}` syntax is handled at the moment in input URLs. That means
+  that if you're using numbered values (`\{0}`, `\{1}`, etc.) or named
+  variables, they will appear as is in the output HTML.
+
+- Firefox handles only one keyword (shortcut) per bookmark, therefore
+  `searchproviders2html` will retain only the *first* keyword from the
+  `.desktop` file.
