119 | # | |
120 | # This function returns an array of files corresponding to a set of tags | |
121 | # given with the options "TAGS". The value of this option can be a single | |
122 | # word, or an array of several words, which work as inclusive or exclusive | |
123 | # selectors. Inclusive selectors are used to add one more set of files to | |
124 | # the returned array, while exclusive selectors limit the set of files added | |
125 | # to the array. The recognised tag values are: | |
126 | # | |
127 | # 'public_manual' - inclusive selector, adds public manuals to the | |
128 | # returned array of files. | |
129 | # 'internal_manual' - inclusive selector, adds internal manuals to the | |
130 | # returned array of files. | |
131 | # 'manual' - inclusive selector, adds any manual to the returned | |
132 | # array of files. This is really a shorthand for | |
133 | # 'public_manual' and 'internal_manual' combined. | |
134 | # 'public_header' - inclusive selector, adds public headers to the | |
135 | # returned array of files. | |
136 | # 'header' - inclusive selector, adds any header file to the | |
137 | # returned array of files. Since we currently only | |
138 | # care about public headers, this is exactly | |
139 | # equivalent to 'public_header', but is present for | |
140 | # consistency. | |
