@enumerate: Making a Numbered or Lettered List@enumerate is like @itemize (see @itemize), except that the labels on the items are
successive integers or letters instead of bullets.
  
Write the @enumerate command at the beginning of a line.  The
command does not require an argument, but accepts either a number or a
letter as an option.  Without an argument, @enumerate starts the
list with the number 1.  With a numeric argument, such as
3, the command starts the list with that number.  With an upper
or lower case letter, such as a or A, the command starts
the list with that letter.
  
Write the text of the enumerated list in the same way as an itemized
list: write a line starting with @item at the beginning of
each paragraph that you want enumerated.  It is ok to have text
following the @item.
  
You should put a blank line between entries in the list. This generally makes it easier to read the Info file.
Here is an example of @enumerate without an argument:
     @enumerate
     @item
     Underlying causes.
     
     @item
     Proximate causes.
     @end enumerate
     
This produces:
Here is an example with an argument of 3:
     @enumerate 3
     @item
     Predisposing causes.
     
     @item
     Precipitating causes.
     
     @item
     Perpetuating causes.
     @end enumerate
     
This produces:
Here is a brief summary of the alternatives.  The summary is constructed
using @enumerate with an argument of a.
@enumerate
     Without an argument, produce a numbered list, starting with the number 1.
@enumerate positive-integerWith a (positive) numeric argument, start a numbered list with that number. You can use this to continue a list that you interrupted with other text.
@enumerate upper-case-letterWith an upper case letter as argument, start a list in which each item is marked by a letter, beginning with that upper case letter.
@enumerate lower-case-letterWith a lower case letter as argument, start a list in which each item is marked by a letter, beginning with that lower case letter.
You can also nest enumerated lists, as in an outline.
