-@section Constructors
-Classes in C++ have 'constructors' and 'destructors'. These are
-functions which are called automatically by the language whenever data
-of a class is created or destroyed. Class data which is static data
-may also be have a type which requires 'construction', the contructor
-must be called before the data can be referenced, so the contructor
-must be called before the program begins.
-
-The common solution to this problem is for the compiler to call a
-magic function as the first statement @code{main}. This magic
-function, (often called @code{__main}) runs around calling the
-constructors for all the things needing it.
-
-With COFF the compile has a bargain with the linker et al. All
-constructors are given strange names, for example
-@code{__GLOBAL__$I$foo} might be the label of a contructor for the
-class @var{foo}. The solution on unfortunate systems (most system V
-machines) is to perform a partial link on all the .o files, do an
-@code{nm} on the result, run @code{awk} or some such over the result
-looking for strange @code{__GLOBAL__$} symbols, generate a C program
-from this, compile it and link with the partially linked input. This
-process is usually called @code{collect}.
-
-Some versions of @code{a.out} use something called the
-@code{set_vector} mechanism. The constructor symbols are output from
-the compiler with a special stab code saying that they are
-constructors, and the linker can deal with them directly.
-
-BFD allows applications (ie the linker) to deal with constructor
-information independently of their external implimentation by
-providing a set of entry points for the indiviual object back ends to
-call which maintains a database of the contructor information. The
-application can interrogate the database to find out what it wants.
-
-The construction data essential for the linker to be able to perform
-its job are:
-
-@itemize @bullet
-@item asymbol
-The asymbol of the contructor entry point contains all the information
-necessary to call the function.
-@item table id
-The type of symbol, ie is it a contructor, a destructor or something
-else someone dreamed up to make our lives difficult.
-@end itemize
-
-This module takes this information and then builds extra sections
-attached to the bfds which own the entry points. It creates these
-sections as if they were tables of pointers to the entry points, and
-builds relocation entries to go with them so that the tables can be
-relocated along with the data they reference.

+DESCRIPTION
+ Classes in C++ have 'constructors' and 'destructors'. These
+ are functions which are called automatically by the language
+ whenever data of a class is created or destroyed. Class data
+ which is static data may also be have a type which requires
+ 'construction', the contructor must be called before the data
+ can be referenced, so the contructor must be called before the
+ program begins.
+
+ The common solution to this problem is for the compiler to
+ call a magic function as the first statement <<main>>.
+ This magic function, (often called <<__main>>) runs around
+ calling the constructors for all the things needing it.
+
+ With COFF the compile has a bargain with the linker et al.
+ All constructors are given strange names, for example
+ <<__GLOBAL__$I$foo>> might be the label of a contructor for
+ the class @var{foo}. The solution on unfortunate systems
+ (most system V machines) is to perform a partial link on all
+ the .o files, do an <<nm>> on the result, run <<awk>> or some
+ such over the result looking for strange <<__GLOBAL__$>>
+ symbols, generate a C program from this, compile it and link
+ with the partially linked input. This process is usually
+ called <<collect>>.
+
+ Some versions of <<a.out>> use something called the
+ <<set_vector>> mechanism. The constructor symbols are output
+ from the compiler with a special stab code saying that they
+ are constructors, and the linker can deal with them directly.
+
+ BFD allows applications (ie the linker) to deal with
+ constructor information independently of their external
+ implimentation by providing a set of entry points for the
+ indiviual object back ends to call which maintains a database
+ of the contructor information. The application can
+ interrogate the database to find out what it wants. The
+ construction data essential for the linker to be able to
+ perform its job are:
+
+ o asymbol
+ The asymbol of the contructor entry point contains all the
+ information necessary to call the function.
+
+ o table id
+ The type of symbol, ie is it a contructor, a destructor or
+ something else someone dreamed up to make our lives difficult.
