title: busybox in embedded linux shows "applet not found"
body: <p>I compiled busybox myself,and I put it in our embedded linux. But I have some questions.</p>
  
  <p>Question 1:When I try to use some command such as gzip,it prints "gzip: applet not found".While I checked the menuconfig of busybox,I make sure that I've selected "gzip".</p>
  
  <p>Question 2:I used to work with VIM,but busybox just provide VI.So I make a link VIM to VI,but when I typed vim and run it,it also show "vim: applet not found".</p>
  
  <p>Anybody can help me with this problem that "applet not found"? Thank you very much.</p>
  
  <p>PS:I'm confused with the "applet" of busybox,what it is? Like "applet" in java?</p>
