- * Imake takes a template makefile (Imake.template) and runs cpp on it
- * producing a temporary makefile in /usr/tmp. It then runs make on
+ * Imake takes a template makefile (Imake.tmpl) and runs cpp on it
+ * producing a temporary makefile in /tmp. It then runs make on
* this pre-processed makefile.
* Options:
* -D define. Same as cpp -D argument.
* -I Include directory. Same as cpp -I argument.
* -T template. Designate a template other
- * than Imake.template
- * -s show. Show the produced makefile on the standard
+ * than Imake.tmpl
+ * -s[F] show. Show the produced makefile on the standard
* output. Make is not run is this case. If a file
* argument is provided, the output is placed there.
+ * -e[F] execute instead of show; optionally name Makefile F
* -v verbose. Show the make command line executed.
*
* Environment variables:
*
- * IMAKEINCLUDE Include directory to use in addition to
- * "." and "/usr/lib/local/imake.include".
+ * IMAKEINCLUDE Include directory to use in addition to "."
* IMAKECPP Cpp to use instead of /lib/cpp
* IMAKEMAKE make program to use other than what is
* found by searching the $PATH variable.
* Call this <imakefile>. This gets added to the arguments for
* make as MAKEFILE=<imakefile>.
* 2. Determine the name of the template from the command line (-T)
- * or the default, Imake.template. Call this <template>
+ * or the default, Imake.tmpl. Call this <template>
* 3. Start up cpp an provide it with three lines of input:
- * #define IMAKE_TEMPLATE "<template>"
- * #define INCLUDE_IMAKEFILE "<imakefile>"
+ * #define IMAKE_TEMPLATE " <template> "
+ * #define INCLUDE_IMAKEFILE < <imakefile> >
* #include IMAKE_TEMPLATE
* Note that the define for INCLUDE_IMAKEFILE is intended for
* use in the template file. This implies that the imake is
