Dear Sirs , Free Pascal and Lazarus documentation is contained in three directories : ../fcl , ../lcl , ../rtl with index.html files for each one . I have prepared a simple index.html as a reference to three of those index.html files . If this index.html with fpdoc.css file is kept in the directory containing the fcl , lcl , and rtl directories and used with a browser ( I used Firefox and Internet Explorer ) it shows any part easily . Within Lazarus Help menu , an "Off-Line Help" item may be included and this index.html file may be attached to it . In that way , it will be possible to view any help part if help documentation is stored into lazarus directory and file names are adjusted with respect to designed directory structure . Thank you very much , Mehmet Erol Sanliturk Reference for package 'fcl' Free Pascal FCL: Free Component Library Units Free Component Library <http://fcl/index.html> Units implementing Free Pascal Free Component Library Description The Free Component Library is a series of units that implemenent various classes and non-visual components for use with Free Pascal. They are building blocks for non-visual and visual programs, such as designed in Lazarus. The TDataset descendents have been implemented in a way that makes them compatible to the Delphi implementation of these units. There are other units that have counterparts in Delphi, but most of them are unique to Free Pascal. Reference for package 'lcl' Free Pascal LCL: Lazarus Component Library Units Lazarus Component Library <http://lcl/index.html> Units implementing Lazarus Component Library Description The Lazarus Component Library is a set of visual components to create gui applications. Reference for package 'rtl' Free Pascal RTL: Free Pascal Run-Time Library Units Free Pascal Run-Time Library <http://rtl/index.html> Units implementing Free Pascal Run-Time Library Description The Run-Time Library is the basis of all Free Pascal programs. It contains the basic units that most programs will use, and are made available on all platforms supported by Free pascal (well, more or less). There are units for compatibility with the Turbo Pascal Run-Time library, and there are units for compatibility with Delphi. On top of these two sets, there are also a series of units to handle keyboard/mouse and text screens in a cross-platform way. Other units include platform specific units that implement the specifics of a platform, these are usually needed to support the Turbo Pascal or Delphi units. Units that fall outside the above outline do not belong in the RTL, but should be included in the packages, or in the FCL.
