Usage: autoconf [OPTION] ... [TEMPLATE-FILE]
|
|
|
|
Generate a configuration script from a TEMPLATE-FILE if given, or
|
|
\`configure.in' by default. Output is sent to the standard output if
|
|
TEMPLATE-FILE is given, else into \`configure'.
|
|
|
|
If the option \`--trace' is used, no configuration script is created.
