Added doc for bin/vim-bx

 one second takes, it can serve as a snippet for Perl `&stamp()`.
 
 
+### vim-bx ###
+
+Wrapper around vim to store timestamps for certain files before edit and
+restore them afterwardds.
+
+This is designed for my bloxsom files, therefore it's hard-coded to look
+for files that contain my blosxom path in the pattern; however, this can
+easily be altered.
+
+The background is that Blosxom blogging system stores articles as plain files,
+and uses the file stamp as article date.  I don't want articles to pop-up
+just because I did a minor typo-fix later.
