  [33X[0;0Yrespectively.[133X
  
  [33X[0;0YDo  this  in a directory called [21X[11Xpkg[111X[121X, preferably (but not necessarily) in the
  [21X[11Xpkg[111X[121X  subdirectory  of  your  [5XGAP[105X  4  installation. It creates a subdirectory
  called [21X[11Xio[111X[121X.[133X
  
  [33X[0;0YThe package will not work without the following compilation step.[133X
  
  [33X[0;0YTo compile the C part of the package do (in the [11Xpkg[111X directory)[133X
  
      cd io
      ./configure
      make
  
  [33X[0;0YIf  you installed the package in another [21X[11Xpkg[111X[121X directory than the standard [21X[11Xpkg[111X[121X
  directory  in  your  [5XGAP[105X  4  installation,  then  you have to do two things.
  Firstly during compilation you have to use the option [10X--with-gaproot=PATH[110X of
  the [11Xconfigure[111X script where [21XPATH[121X is a path to the main [5XGAP[105X root directory (if
  not given the default [21X[11X../..[111X[121X is assumed).[133X
  
  [33X[0;0YSecondly  you  have to specify the path to the directory containing your [21X[11Xpkg[111X[121X
  directory  to  [5XGAP[105X's  list  of directories. This can be done by starting [5XGAP[105X
  with  the [21X[11X-l[111X[121X command line option followed by the name of the directory and a
  semicolon.  Then  your  directory  is  prepended  to the list of directories
  searched.  Otherwise the package is not found by [5XGAP[105X. Of course, you can add
  this option to your [5XGAP[105X startup script.[133X
  
  
  [1X2.1 [33X[0;0YRecompiling the documentation[133X[101X
  
  [33X[0;0YRecompiling  the  documentation  is possible by the command [21X[11Xgap makedoc.g[111X[121X in
  the [11Xio[111X directory. But this should not be necessary.[133X
