For some languages, a list of global tags is loaded when the corresponding filetype
is first used. Currently these are for:

Currently this is not yet supported for Pascal, PHP and LaTeX filetypes.

You can generate your own global tags files by parsing a list of source files.
The command is:
</p><p>
geany -g <Tag File><File list>

For C/C++ tag files, <codeclass="filename">gcc</code> and <codeclass="filename">grep</code> are
required, so that header files can be preprocessed to include
any other headers they depend upon.

For C/C++ files, the environment variable CFLAGS should be set with appropriate
<codeclass="literal">-I/path</code> include paths.
The following example works with the <codeclass="filename">bash</code> shell, generating
