activated at.

-.BI "-std=" standard
-Use the specified standard for parsing QC code. The following standards

-.IR gmqcc , qcc , fteqcc
-.TP
.BI -W warning "\fR, " "" -Wno- warning
Enable or disable a warning.
.TP
.B -Wall
Enable all warnings. Overrides preceding -W parameters.
.TP
+.BR -Werror ", " -Wno-error
+Controls whether or not all warnings should be treated as errors.
+.TP

+Controls whether a specific warning should be an error.
+.TP
.B -Whelp
List all possible warn flags.
.TP
.B -nocolor
Disables colored output
.TP
+.BI -config= file
+Use an ini file to read all the -O, -W and -f flag from. See the
+CONFIG section about the file format.
+.TP
.BI "-redirout=" file
Redirects standard output to a \fIfile\fR
.TP
-.BI "-rediterr=" file
+.BI "-redirerr=" file
Redirects standard error to a \fIfile\fR
+.TP
+.BI "-std=" standard
+Use the specified standard for parsing QC code. The following standards
+are available:
+.IR gmqcc , qcc , fteqcc
+Selecting a standard also implies some -f options and behaves as if
+those options have been written right after the -std option, meaning
+if you changed them before the -std option, you're now overwriting
+them.

.SH Warnings
.TP
.B -Wunused-variable
without enclosing parenthesis, since this is most likely not what you
actually want. We recommend the \fI-fcorrect-ternary\fR option.
.TP
+.B -Wunknown-pragmas
+Warn when encountering an unrecognized \fI#pragma\fR line.
+.TP
+.B -Wunreachable-code
+Warn about unreachable code. That is: code after a return statement,
+or code after a call to a function marked as 'noreturn'.
+.TP
.B -Wdebug
Enable some warnings added in order to help debugging in the compiler.
You won't need this.
Use C's operator precedence for ternary expressions. Unless your code
depends on fteqcc-compatible behaviour, you'll want to use thi
soption.
+.TP
+.B -fsingle-vector-defs
+Normally vectors generate 4 defs, once for the vector, and once for
+its components with _x, _y, _z suffixes. This option
+prevents components from being listed.
+.SH CONFIG
+The configuration file is similar to regular .ini files. Comments
+start with hashtags or semicolons, sections are written in square
+brackets and in each section there can be arbitrary many key-value
+pairs.
+.sp
+There are 3 sections currently:
+.IR flags ", " warnings ", and " optimizations .
+They contain a list of boolean values of the form `VARNAME = true` or
+`VARNAME = false`. The variable names are the same as for the
+corresponding -W, -f or -O flag written with only capital letters and
+dashes replaced by underscores.
+.sp
+Here's an example:
+.in +4
+.nf
+# a GMQCC configuration file
+[flags]
+ FTEPP = true
+ ADJUST_VECTOR_FIELDS = false
+ LNO = true
+
+[warnings]
+ UNUSED_VARIABLE = false
+ USED_UNINITIALIZED = true
+
+[optimizations]
+ PEEPHOLE = true
+ TAIL_RECURSION = true
