.SH NAME
GP2C \- The GP to C compiler 
.SH DESCRIPTION
gp2c [-ghfltvydWSTGV] [-i N] [-o <file>] [-p <prefix>] [file.gp]

gp2c is a program that translate GP code to C code that use the libpari
library. It tries to generate code looking like the PARI source code.

.SS "user option:"
.HP
\fB\-o\fR <file> : Place output in file <file>.
.HP
\fB\-g\fR : Generate automatic garbage collection code.
.HP
\fB\-iN\fR: Set indentation level to N spaces (default 2).
.HP
\fB\-W\fR : Output warning about types and global variables usage.
.HP
\fB\-C\fR : Generate range checking code.
.HP
\fB\-L\fR : Generate #line directive for better C compiler messages.
.HP
\fB\-p\fR <prefix>: Prefix user-defined symbol by <prefix> to avoid conflict.
.HP
\fB\-s\fR <suffix>: Add suffix <suffix> to GP install names of functions.
.HP
\fB\-S\fR: Assume strict declarations for functions.
.SS "query options:"
.HP
\fB\-h\fR : This help.
.HP
\fB\-f\fR : Dump information about functions to stderr.
.HP
\fB\-l\fR : Output the list of functions known to the compiler.
.HP
\fB\-t\fR : Output the table of types known to the compiler.
.HP
\fB\-v\fR : Output version information and exit.
.SS "debugging options:"
.HP
\fB\-d\fR : Increase debugging level.
.HP
\fB\-y\fR : Switch parser to debug mode.
.HP
\fB\-T\fR : Output syntactic tree in treetool format.
.HP
\fB\-TT\fR : Output syntactic tree in VCG/GRL format.
.HP
\fB\-G\fR : Generate GP code in place of C code. Don't smile.
.HP
\fB\-V\fR : Do not clean up variables.
.PP
file.gp: file to be processed, default to stdin.
The generated C code is output to stdout unless option \fB\-o\fR is
used.

See the script \fIgp2c-run\fR for an automated compilation process.
