"NAME\n"
" regapi - perform certain actions on the wine registry.\n"
"\n"
"SYNOPSIS\n"
" regapi commandName [-force] < file\n"
"\n"
"DESCRIPTION\n"
" regapi modifies settings in the wine registry. It processes\n"
" the given commandName for every line in the stdin data stream.\n"
" Input data format may vary depending on the commandName\n"
" (see INPUT FILE FORMAT).\n"
"\n"
"OPTIONS\n"
" commandName\n"
" Instruct regapi about what action to perform on the data stream.\n"
" Currently, only setValue and queryValue are supported and\n"
" implemented.\n"
"\n"
" -force\n"
" When provided the action will be performed anyway. This may\n"
" have a different meaning depending on the context. For example,\n"
" when providing -force to setValue, the value is set even if it\n"
" was previously set to another value.\n"
"\n"
" < file\n"
" STDIN channel, provide a file name with line of the appropriate\n"
" format.\n"
"\n"
"INPUT FILE FORMAT\n"
"\n"
" setValue\n"
" The input file is in format, obtained from regedit.exe export.\n"
"\n"
" [KEY_CLASS\\Some\\Path\\For\\A\\Key]\n"
" \"Value1\"=\"Data1\"\n"
" \"Value2\"=\"Data2\"\n"
" \"Valuen\"=\"Datan\"\n"
" ...\n"
"\n"
" queryValue\n"
" The input file format required by the queryValue command is\n"
" similar to the one required by setValue. The only\n"
" difference is that you only provide the value name.\n"
"\n"
" [KEY_CLASS\\Some\\Path\\For\\A\\Key]\n"
" \"Value1\"\n"
" \"Value2\"\n"
" \"Valuen\"\n"
" ...\n"
" registerDLL\n"
" The input file format is a list of DLLs to register\n"
"\n"
" unregisterDLL\n"
" The input file format is a list of DLLs to unregister\n"
