Made documentation more consistent

 ALIASES += sideeffect="\par Side Effects:\n" 

\endverbatim

 will allow you to

 put the command \\sideeffect (or \@sideeffect) in the documentation, which 

 put the command `\sideeffect` (or `@sideeffect`) in the documentation, which 

 will result in a user-defined paragraph with heading <b>Side Effects:</b>.

Note that you can put \\n's in the value part of an alias to insert newlines.

Note that you can put `\n`'s in the value part of an alias to insert newlines.

Also note that you can redefine existing special commands if you wish.

\section custcmd_complex Aliases with arguments

Aliases can also have one or more arguments. In the alias definition you then need

to specify the number of arguments between curly braces. In the value part of the

definition you can place \\x markers, where 'x' represents the argument number starting

definition you can place `\x` markers, where '`x`' represents the argument number starting

with 1.

Here is an example of an alias definition with a single argument:

where the command with a single argument would still work as shown before.

Aliases can also be expressed in terms of other aliases, e.g. a new command

\\reminder can be expressed as a \\xrefitem via an intermediate \\xreflist command

`\reminder` can be expressed as a \ref cmdxrefitem "\\xrefitem" via an intermediate `\xreflist` command

as follows:

\verbatim

ALIASES += xreflist{3}="\xrefitem \1 \"\2\" \"\3\" " \

ALIASES += reminder="\xreflist{reminders,Reminder,Reminders}" \

ALIASES += xreflist{3}="\xrefitem \1 \"\2\" \"\3\" "

ALIASES += reminder="\xreflist{reminders,Reminder,Reminders}"

\endverbatim

Note that if for aliases with more than one argument a comma is used as a separator,

\verbatim

\l{SomeClass,Some text\, with an escaped comma} 

\endverbatim

given the alias definition of \\l in the example above.

given the alias definition of `\l` in the example above.
