This is taken from doc/filter.txt. Note the final sentence.

  18. Obeying commands conditionally
  
  Most of the power of filtering comes from the ability to test conditions
  and obey different commands depending on the outcome. The "if" command is
  used to specify conditional execution, and its general form is
  
    if    <condition>
    then  <commands>
    elif  <condition>
    then  <commands>
    else  <commands>
    endif
  
  There may be any number of "elif"-"then" sections (including none) and the
  "else" section is also optional. Any number of commands, including nested
  "if" commands, may appear in any of the <commands> sections.
