|

106 | problems and creates a <filename>configure.scan</filename> file that serves as
|

124 | <para>can be helpful when writing a

125 | <filename>configure.in</filename> for a software package. It prints the

126 | identifiers that the package uses in C preprocessor conditionals. If a package
|
---|
127 | has already been set up to have some portability, this program can help to
|
---|
128 | determine what <command>configure</command> needs to check. It can fill
|
---|
129 | in some gaps in a <filename>configure.in</filename> file generated by
|
---|
130 | autoscan.</para>
