139 | |
140 Delete files not known to mercurial, this is useful to test local and | |
141 uncommitted changes in the otherwise clean source tree. | |
142 | |
143 This means that purge will delete: | |
144 - Unknown files: files marked with "?" by "hg status" | |
145 - Ignored files: files usually ignored by Mercurial because they match | |
146 a pattern in a ".hgignore" file | |
147 - Empty directories: infact Mercurial ignores directories unless they | |
148 contain files under source control managment | |
149 But it will leave untouched: | |
150 - Unmodified tracked files | |
151 - Modified tracked files | |
152 - New files added to the repository (with "hg add") | |
153 | |
154 If directories are given on the command line, only files in these | |
155 directories are considered. | |
156 | |
157 Be careful with purge, you could irreversibly delete some files you | |
158 forgot to add to the repository. If you only want to print the list of | |
159 files that this program would delete use the -vn options. | |
