# Sample files for the test
src_text = <<'EOS'
This is a source file.
EOS

sample_c = <<'EOS'
#include <stdio.h>

int
main (int argc, char **argv) {
  printf ("Hello world.\n");
}
EOS

sec1_text = <<'EOS'
This is a test file.
The sorce of `sample.c` is:

@@@include
sample.c main
@@@

It is the simplest C program.
EOS

sec2_text = <<'EOS'
To compile the C source file `sample.c`, type:

~~~
$ gcc sample.c
~~~

Then executable file `a.out` is generated.

@@@shell
ls
@@@

To execute it, type:

~~~
$ ./a.out
~~~

The source code is in [Section 1](sec1.src.md)

sec05_text = <<'EOS'

- Linux OS like Ubuntu or Debian.
- gcc
