161	" regapi commandName [-force] < file\n"
162	"\n"
163	"DESCRIPTION\n"
164	" regapi modifies settings in the wine registry. It processes\n"
165	" the given commandName for every line in the stdin data stream.\n"
166	" Input data format may vary depending on the commandName\n"
167	" (see INPUT FILE FORMAT).\n"
168	"\n"
169	"OPTIONS\n"
170	" commandName\n"
171	" Instruct regapi about what action to perform on the data stream.\n"
172	" Currently, only setValue and queryValue are supported and\n"
173	" implemented.\n"
174	"\n"
175	" -force\n"
176	" When provided the action will be performed anyway. This may\n"
177	" have a different meaning depending on the context. For example,\n"
178	" when providing -force to setValue, the value is set even if it\n"
179	" was previously set to another value.\n"
180	"\n"
181	" < file\n"
182	" STDIN channel, provide a file name with line of the appropriate\n"
183	" format.\n"
184	"\n"
185	"INPUT FILE FORMAT\n"
186	"\n"
187	" setValue\n"
188	" The input file format required by the setValue command is similar\n"
189	" to the one obtained from regedit.exe export option. The only\n"
190	" difference is that multi line values are not supported, the\n"
191	" value data must be on a single line.\n"
192	"\n"
193	" [KEY_CLASS\\Some\\Path\\For\\A\\Key]\n"
194	" \"Value1\"=\"Data1\"\n"
195	" \"Value2\"=\"Data2\"\n"
196	" \"Valuen\"=\"Datan\"\n"
197	" ...\n"
198	"\n"
199	" queryValue\n"
200	" The input file format required by the queryValue command is\n"
201	" similar to the one required by setValue. The only\n"
202	" difference is that you only provide the value name.\n"
203	"\n"
