+.SH NAME
+ccfilter \- a compiler's output filter for vim quickfix
+.SH SYNOPSIS
+ccfilter [
+.B <options>
+]
+.SH DESCRIPTION
+The ccfilter utility "filters" the output of several compilers
+and makers (make/gmake) from several platforms (see NOTES below)
+to a standardized format which easily fits in vim's quickfix
+feature. For further details, see in vim ":help quickfix".
+.PP
+ccfilter reads
+.B 'stdin'
+and outputs to
+.B 'stdout'
+\.
+.PP
+The need for ccfilter is clear, as some compilers have irregular
+and/or multiple line error messages (with the relevant information on
+line 2), which makes it impossible for the errorformat to correctly
+display them !
+
+When working on different platforms, and with different compilers,
+ccfilter eases the utilization of quickfix, due to its standardized
+output, allowing to have in .vimrc a plain
+.br
+.B \ \ \ \ :set\ errorformat=%f:%l:%c:%t:%m
+
+.SH USAGE
+When using ccfilter, one would include the following lines in .vimrc:
+.br
+.B \ \ \ \ :set shellpipe=\\\\|&ccfilter\\\\>
+.br
+.B \ \ \ \ :set errorformat=%f:%l:%c:%t:%m
+
+.SH OPTIONS
+.TP 16
+-c
+Decrement column by one. This may be needed, depending on
+the compiler being used.
+.TP
+-r
+Decrement row by one.  This may be needed, depending on
+the compiler being used.
+.TP
+-v
+Verbose (Outputs also invalid lines).
+This option makes ccfilter output also the lines that
+couldn't be correctly parsed. This is used mostly for
+ccfilter debugging.
+.TP
+-o <COMPILER>
+Treat input as <COMPILER>'s output.
+Even when configuring ccfilter to assume a default
+COMPILER, sometimes it's helpful to be able to specify
+the COMPILER used to generate ccfilter's input.
+For example, when cross-compiling on a network from a
+single machine.
+.TP
+-h
+Shows a brief help, describing the configured default COMPILER
+and the valid parameters for COMPILER.
+
+.SH NOTES
+Currently, ccfilter accepts output from several compilers, as
+described below:
+.TP 10
+GCC
+GCC compiler
+.TP
+AIX
+AIX's C compiler
+.TP
+ATT
+AT&T/NCR's High Performance C Compiler
+.TP
+IRIX
+IRIX's MIPS/MIPSpro C compiler
+.TP
+SOLARIS
+SOLARIS's SparcWorks C compiler
+.TP
+HPUX
+HPUX's C compiler
