| 32 | .SH DESCRIPTION
|
|---|
| 33 | .PP
|
|---|
| 34 | .I Make
|
|---|
| 35 | is a program that is normally used for developing large programs consisting of
|
|---|
| 36 | multiple files.
|
|---|
| 37 | It keeps track of which object files depend on which source and header files.
|
|---|
| 38 | When called, it does the minimum amount of recompilation to bring the target
|
|---|
| 39 | file up to date.
|
|---|
| 40 | .PP
|
|---|
| 41 | The file dependencies are expected in
|
|---|
| 42 | .I makefile
|
|---|
| 43 | or
|
|---|
| 44 | .I Makefile ,
|
|---|
| 45 | unless another file is specified with \fB\-f\fR.
|
|---|
| 46 | .I Make
|
|---|
| 47 | has some default rules built in, for example, it knows how to make
|
|---|
| 48 | .I .o
|
|---|
| 49 | files
|
|---|
| 50 | from
|
|---|
| 51 | .I .c
|
|---|
| 52 | files.
