  
  [1X4. Installation and auxiliary functions[0X
  
  
  [1X4.1 Requirements[0X
  
  The  [5XResClasses[0X  package needs at least [5XGAP[0X 4.4.7 and [5XGAPDoc[0X 0.99999 [LN07].
  It can be used under UNIX, under Windows and on the MacIntosh. [5XResClasses[0X is
  completely  written in the [5XGAP[0X language and does neither contain nor require
  external binaries.
  
  
  [1X4.2 Installation[0X
  
  Like  any  other  [5XGAP[0X  package,  [5XResClasses[0X  must  be  installed  in the [11Xpkg[0X
  subdirectory of the [5XGAP[0X distribution. This is accomplished by extracting the
  distribution  file  in this directory. By default, the package [5XResClasses[0X is
  autoloaded.  If  you have switched autoloading of packages off, you can load
  [5XResClasses[0X via [10XLoadPackage( "resclasses" );[0X.
  
  
  [1X4.3 The testing routine[0X
  
  [1X4.3-1 ResClassesTest[0X
  
  [2X> ResClassesTest( [0X[3X[0X[2X ) _______________________________________________[0Xfunction
  [6XReturns:[0X  Nothing.
  
  Performs  tests  of  the [5XResClasses[0X package. Errors, i.e. differences to the
  correct  results  of the test computations, are reported. The processed test
  files are in the directory [11Xpkg/resclasses/tst[0X.
  
  
  [1X4.4 Building the manual[0X
  
  [1X4.4-1 ResClassesBuildManual[0X
  
  [2X> ResClassesBuildManual( [0X[3X[0X[2X ) ________________________________________[0Xfunction
  [6XReturns:[0X  Nothing.
  
  This  function  is  a  development  tool  which  builds  the  manual  of the
  [5XResClasses[0X package in the file formats LaTeX, PDF, HTML and ASCII text. This
  is accomplished using the [5XGAPDoc[0X package by Frank Lübeck and Max Neunhöffer.
  Building  the manual is possible only on UNIX systems and requires PDFLaTeX.
  As  all  files  generated  by this function are included in the distribution
  file anyway, users will not need it.
  
  
  [1X4.5 SendEmail and EmailLogFile[0X
  
  [1X4.5-1 SendEmail[0X
  
  [2X> SendEmail( [0X[3Xsendto, copyto, subject, text[0X[2X ) _______________________[0Xfunction
  [6XReturns:[0X  Zero  if  everything  worked  correctly, and a system error number
            otherwise.
  
  Sends  an  e-mail with subject [3Xsubject[0X and body [3Xtext[0X to the addresses in the
  list  [3Xsendto[0X,  and  copies  it  to  those  in the list [3Xcopyto[0X. The first two
  arguments must be lists of strings, and the latter two must be strings.
  
  As  most system-related functions, [10XSendEmail[0X works only under UNIX. Further,
  the computer must of course be connected to the internet.
  
  [1X4.5-2 EmailLogFile[0X
  
  [2X> EmailLogFile( [0X[3Xaddresses[0X[2X ) ________________________________________[0Xfunction
  [6XReturns:[0X  Zero  if  everything  worked  correctly, and a system error number
            otherwise.
  
  Sends the current log file by e-mail to [3Xaddresses[0X, if [5XGAP[0X is in logging mode
  and  one  is  working  under  UNIX, and does nothing otherwise. The argument
  [3Xaddresses[0X  must  be  either  a  list  of e-mail addresses or a single e-mail
  address. Long log files are abbreviated, i.e. if the log file is larger than
  64KB,  then  any  output  is  truncated at 1KB, and if the log file is still
  longer than 64KB afterwards, it is truncated at 64KB.
